Molly, a form of ecstasy, is one of the most popular club drugs in the world. However, molly is a dangerous substance that can seriously harm an individual’s mind, body, and life.

While users consume the drug for the pleasant short-term effects, the long-term effects of molly can be disastrous.

What Is Ecstasy? What Is Molly?

Ecstasy is the most common street name for MDMA, which is the abbreviated form of 3,4-methylenedioxymethamphetamine. It is a derivative of methamphetamine with a molecular structure similar to mescalin. That means it acts as both a stimulant and a dissociative hallucinogenic.

Ecstasy was first created in the early 1900s and initially used to help stop internal bleeding, then later as another version of adrenaline, and eventually for its psychoactive effects. The drug became popular in the 1980s through its use in couples counseling.

Other common names for ecstasy include X, ex, XTC, biscuit, Adam, disco biscuit, skittles, love drug, hug drug, rolls, and candy.

Ecstasy is a Schedule I drug, meaning it is illegal to possess or distribute in the U.S.

Although Schedule I drugs are said to have a high potential for abuse, there is extensive testing for ecstasy in trauma and PTSD therapy, and there is a good chance the drug will be down-scheduled because of studies like one published in Nature Medicine.

Ecstasy is available in many forms, each known by a different name. One of the most common forms is a ground powder known as molly. People usually take molly in pill capsules or dissolve it into water to create “molly water.”

Molly was initially popular because many thought it to be purer than pressed pills, sometimes called “beans.” However, molly is often cut with other drugs.

Short-Term Effects of Molly

Molly affects the body’s central nervous system. It influences the levels of serotonin, dopamine, and norepinephrine in the body, meaning the effects of molly are both physical and mental.

This drug is popular in club, rave, and hip-hop cultures (among others) because of its pleasant, short-term effects, but many users do not realize the effects it can have on the body and the brain long term.

Some of the most common psychological effects of MDMA include:

Mood arousal
Sexual arousal
A sense of wellbeing
Euphoria
A sense of excitement
Feelings of peace or calm
Extra sensitivity
Increased energy
Increase physical and emotional feelings
Heightened sociability and closeness
Relaxation
Increased empathy
Insomnia

Some of the most common physical effects of MDMA include:

Blurry/double vision
Profuse sweating
Loss of control of bodily movements
Changes in perception
Dry mouth
Dehydration
Mild intoxication
Muscle tension, especially in the jaw area

Ecstasy causes a mass release of “feel-good” chemicals, like serotonin, which cause the short-term effects of the drug. Afterward, the brain is depleted of those “feel-good” chemicals, which can put individuals into a state of intense depression (sometimes called the “comedown”) for several days.

The comedown is typically at its worst about two days after the last use of the drug. In fact, there is a phenomenon among molly users known as “Suicide Tuesday” because so many people experience extreme depression or commit suicide on that day after a weekend of partying.

Long-Term Effects of Molly Use

Long-term use of ecstasy (molly) can have a range of negative impacts on the mind and body, including:

Neurotoxicity

Difficulties paying attention, concentrating, and/or problem-solving

Dangers of Molly / Ecstasy

Ecstasy causes the heart rate to increase, which can be dangerous, especially for those with heart conditions.

It also increases body temperature, which can cause dehydration and damage the liver and kidneys. Individuals taking the drug may forget to drink water and can have a heat stroke or worse.

Most importantly, ecstasy overdose is possible and, at times, life-threatening. It can cause:

Heart arrhythmias
Overheating
Seizures
Muscle breakdown and kidney injury from hyperthermia
Potentially fatal Serotonin syndrome

Signs someone could be overdosing on ecstasy include:

High fever
Tremors
Seizures
Irregular heartbeat
Unconsciousness

Seek medical attention immediately if you believe someone is overdosing on ecstasy.

How Molly Usage Impacts the Brain

Molly has many effects on the brain. MDMA primarily impacts the neurotransmitter serotonin, which plays a key role in mood and emotions, among other functions. MDMA causes an increase in the release of serotonin in the brain, which causes waves, or rolls, of pleasurable sensations.

The serotonin release causes short-term euphoria but also depletes the brain’s serotonin levels, sometimes for several days afterward. Prolonged use may increase the risk of developing mood disorders.

Molly is also neurotoxic and can cause long-term damage to serotonin-producing neurons. MDMA use causes short-term memory impairments, which may persist if usage continues.

The Effects of Ecstasy (Molly) FAQ

How long do the effects of ecstasy/molly last?

How long the effects of ecstasy last will vary depending on how much of the drug was consumed, the user’s tolerance for the drug, and the method of consumption.

In general, the first effects of ecstasy will appear between 20 and 60 minutes after ingestion. This is known as onset. The effects of ecstasy are generally strongest between one to 1.5 hours after ingestion. This period is known as the peak.

The plateau phase, when effects slowly subside from the peak, usually lasts two to three hours.

The comedown, or offset phase, takes place about three to four hours after ingestion. During this time, consciousness returns to normal. Some users may experience an afterglow phase of lingering symptoms after this as well.

There has been very little research conducted on the long-term effects of ecstasy on the brain. However, ecstasy has been proven to be neurotoxic and can cause damage to serotonin-producing neurons.
