How to

  • Oral Ingestion:
    • Onset and Duration: This method has a slower onset of effects, usually taking 30 minutes to an hour to kick in, but the effects can last several hours.
    • Experience: Oral ingestion is often associated with a more gradual and prolonged experience.
  • Insufflation (Snorting):
    • Onset and Duration: Snorting leads to a quicker onset of effects, typically within a few minutes, but the overall duration might be shorter compared to oral ingestion.
    • Experience: The effects are more intense but may last for a shorter duration. This method can be more damaging to the nasal passages.
  • Smoking:
    • Onset and Duration: Smoking provides an almost immediate onset of effects, but like snorting, the duration is often shorter.
    • Experience: Effects from smoking can be intense and rapid, but this method carries additional risks such as lung damage.
  • Injection:
    • Onset and Duration: Injection leads to immediate effects, with both high intensity and risk.
    • Experience: This method is the most risky, increasing the likelihood of addiction and the potential for serious health complications, including the risk of contracting blood-borne diseases.
  • Sublingual (Under the Tongue):
    • Onset and Duration: Sublingual administration has a quicker onset than oral ingestion but slower than snorting or smoking.
    • Experience: The effects are more controlled than smoking or injection but more intense than oral ingestion.

History & Stats

3-MMC emerged in the early 21st century as part of the wave of new psychoactive substances. It gained popularity as an alternative to other banned stimulants, such as mephedrone (4-MMC).

Accurate statistics on 3-MMC use are challenging to obtain due to its status as a new and relatively under-researched substance. However, it has been reported in various contexts, including in drug seizures and hospital admissions.


Common myths may include the belief that 3-MMC is safe because it’s legal in some places, or that it’s a harmless party drug. The reality is that its legal status doesn’t equate to safety, and its use can pose significant health risks.

It’s important to approach 3-MMC with caution and understand its effects and risks. Have you had an experience with 3-MMC and need support to integrate it? Or do you plan on having one and want the best setting possible? Book a session with one of our coaches.
