Mephedrone & Sleeping pills​

Mephedrone, also known as 4-methylmethcathinone or 4-MMC, is a synthetic stimulant belonging to the cathinone class of psychoactive substances. Structurally related to compounds found in the khat plant, mephedrone shares similarities with other stimulants like amphetamines and MDMA (ecstasy).

Mephedrone works by increasing the levels of key neurotransmitters in the brain, namely dopamine, serotonin, and norepinephrine. It achieves this by acting as a releasing agent and reuptake inhibitor for these neurotransmitters. Specifically, mephedrone enters presynaptic neurons through transporter proteins and promotes the release of stored neurotransmitters into the synaptic cleft. Simultaneously, it inhibits the reuptake mechanisms that normally remove these neurotransmitters from the synapse, leading to elevated concentrations and prolonged signaling.

The increased dopamine levels contribute to feelings of euphoria, heightened energy, and increased motivation. Elevated serotonin levels enhance mood, empathy, and sociability, while increased norepinephrine leads to heightened alertness and physical stimulation. The combined effect results in a potent stimulant experience with both euphoric and empathogenic properties.

Physiologically, mephedrone can cause a range of effects:

• Increased heart rate (tachycardia) and elevated blood pressure due to sympathetic nervous system stimulation.
• Enhanced alertness, reduced appetite, teeth grinding (bruxism), and potential agitation or anxiety.
• Elevated body temperature (hyperthermia) as a result of increased metabolic activity.
• Nausea or stomach discomfort in some individuals.

Metabolism of mephedrone occurs primarily in the liver, where it is broken down into various metabolites that are excreted through the kidneys. The metabolic pathways involve demethylation, oxidation, and reduction processes facilitated by enzymes such as cytochrome P450.


Sleeping pills, also known as sedatives or hypnotics, are medications designed to help individuals fall asleep faster, stay asleep longer, or achieve better sleep quality. They work by interacting with various neurotransmitter systems in the brain that regulate the sleep-wake cycle. Different classes of sleeping pills have distinct mechanisms of action and are chosen based on the specific sleep issues they address.

One common class of sleeping pills is benzodiazepines, such as temazepam and triazolam. These drugs enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA) by binding to GABA-A receptors in the brain. GABA is an inhibitory neurotransmitter that reduces neuronal activity, promoting relaxation and sleepiness. For example, temazepam binds to GABA-A receptors, increasing the influx of chloride ions into neurons, which hyperpolarizes the cell membrane and makes it less likely to fire. This leads to a calming effect on the central nervous system, helping individuals with insomnia to fall asleep.

Another class is non-benzodiazepine hypnotics, often referred to as "Z-drugs," which include zolpidem, zaleplon, and eszopiclone. Although structurally different from benzodiazepines, they also act on GABA-A receptors but are more selective for subunits associated with sleep regulation. Zolpidem, for instance, binds primarily to the alpha-1 subunit of the GABA-A receptor, promoting sedation without significant muscle relaxation or anti-anxiety effects. This makes it effective for initiating sleep with fewer side effects related to cognition and motor function.

Melatonin receptor agonists, such as ramelteon, mimic the action of melatonin, a hormone produced by the pineal gland that regulates circadian rhythms. Ramelteon selectively binds to melatonin MT1 and MT2 receptors in the suprachiasmatic nucleus of the hypothalamus, an area of the brain responsible for controlling sleep-wake cycles. By activating these receptors, ramelteon helps regulate the timing of sleep, making it useful for individuals with delayed sleep phase syndrome or difficulty falling asleep at the desired time.

Antihistamines, like diphenhydramine and doxylamine, are over-the-counter medications that induce drowsiness by blocking histamine H1 receptors in the brain. Histamine is a neurotransmitter that promotes wakefulness. By inhibiting its action, antihistamines reduce alertness and can help initiate sleep. For example, someone with occasional sleeplessness might take diphenhydramine to help fall asleep. However, antihistamines can cause residual drowsiness the next day and are not recommended for long-term use due to tolerance and side effects like dry mouth and blurred vision.

Some antidepressants with sedative properties, such as trazodone and mirtazapine, are used off-label as sleep aids. Trazodone works by antagonizing serotonin 5-HT2A and alpha-1 adrenergic receptors while inhibiting serotonin reuptake, which contributes to its sedative effects. For instance, a patient with depression and insomnia might be prescribed trazodone to address both conditions simultaneously.

Orexin receptor antagonists, like suvorexant, represent a newer class of sleeping pills. Orexin is a neuropeptide that promotes wakefulness by activating orexin receptors in the brain. Suvorexant blocks these receptors, reducing the activity of wake-promoting neurons. This leads to decreased arousal and facilitates the onset and maintenance of sleep. An individual struggling with middle-of-the-night awakenings might benefit from suvorexant due to its ability to prolong sleep duration.


Combining mephedrone with sleeping pills can lead to significant and potentially dangerous interactions. The stimulant action of mephedrone may counteract the sedative effects of sleeping pills, prompting individuals to consume higher doses of either substance to achieve the desired level of stimulation or sedation. This can increase the risk of overdose and adverse reactions. For example, excessive intake of sleeping pills can lead to profound sedation, respiratory depression, or loss of consciousness, while high doses of mephedrone can cause severe cardiovascular stress, agitation, or psychosis.

Physiologically, the combination can strain the cardiovascular system. Mephedrone's stimulant properties elevate heart rate and blood pressure, while some sleeping pills may cause hypotension or depress respiratory function. The opposing actions can lead to arrhythmias, hypertension, or respiratory complications. Additionally, both substances can affect thermoregulation, potentially resulting in hyperthermia or hypothermia, which can be life-threatening if not promptly addressed.

There is also an increased risk of neurochemical imbalances. Mephedrone elevates serotonin levels, and certain sleeping pills, like some antidepressants used off-label for insomnia (e.g., trazodone), also influence serotonin pathways. The combined effect can raise the potential for serotonin syndrome, a serious condition characterized by symptoms such as agitation, confusion, rapid heart rate, dilated pupils, muscle rigidity, and elevated body temperature.

Cognitively, the mixture can impair judgment, coordination, and reaction times. The sedative effects of sleeping pills may not fully counteract the stimulant-induced alertness from mephedrone, leading to a false sense of sobriety. This can result in risky behaviors, such as driving under the influence or engaging in unsafe activities, increasing the likelihood of accidents or injuries.

Psychologically, combining mephedrone and sleeping pills can exacerbate anxiety, paranoia, mood swings, or lead to acute psychotic episodes. The alteration of multiple neurotransmitter systems may disrupt normal mood regulation and cognitive function. In some cases, individuals may experience severe agitation, hallucinations, or disorientation, requiring medical intervention.

From a metabolic standpoint, both substances are processed by the liver, potentially leading to increased strain on hepatic function. The concurrent use may affect the metabolism and elimination of one or both drugs, leading to higher systemic concentrations and prolonged effects. This can enhance toxicity and the duration of adverse symptoms.


Using sleeping pills to "calm down" after a session of mephedrone requires careful consideration.

While medical supervision is ideal, the following strategies can help:

• Hydration and Nutrition: Stimulants deplete electrolytes and suppress appetite, so rehydrating with water or electrolyte-rich drinks and eating a light, nutritious meal can help.
• Sleep Hygiene: Create a calming environment by dimming lights, reducing noise, and avoiding screens.
• Breathing Exercises and Mindfulness: Deep breathing, progressive muscle relaxation, or guided meditations can calm the nervous system.

If non-drug strategies aren't enough, some options may be safer than others, but they should ideally be taken under medical advice:

• Melatonin: This over-the-counter sleep aid supports the body's natural sleep-wake cycle without the strong sedative effects of prescription sleeping pills.
• Antihistamines: Drugs like diphenhydramine or doxylamine have sedative properties but are milder than prescription options. However, they can cause grogginess the next day.
• Short-acting Benzodiazepines: Drugs like lorazepam or temazepam might be used in acute cases but carry risks of dependence, tolerance, and respiratory depression.
• Avoid Alcohol and Strong Sedatives. Drugs like barbiturates or high doses of benzodiazepines are dangerous in this context.

If you plan to use stimulants like mephedrone, these steps can minimize risks:

1. Keep the next day free to recover, and avoid using additional substances to "come down."
2. Larger doses and prolonged binges increase the severity of the crash and complicate sleep recovery.
3. Let someone know you're using so they can assist if needed.

In light of these considerations, we strongly recommend a meaningful approach to this combination.
