Mixing MDMA (molly) and Methamphetamine (meth)
Unsafe
Both hit the same brain cells, and meth keeps up the heat and dehydration for hours after the MDMA ends. Avoid this combination.
Both are releasers acting on the same neurons, and the neurotoxicity mechanisms are shared — serotonergic and dopaminergic terminals under oxidative and thermal stress at the same time. Methamphetamine's much longer duration means the strain continues for many hours after the MDMA has finished, which is exactly the window where overheating and dehydration do their damage.
This combination carries bodily risk and can go badly psychologically. The headspace part often arrives first and makes the physical part harder to notice.
Headspace vs physical riskWhat to do
- Say what was taken and how much.Responders need it, and in most US states Good Samaritan laws protect both of you from drug possession charges when you call for an overdose.
- Unresponsive: put them on their side, tilt the head back, and stay until help arrives.Never leave someone alone to “sleep it off”.
- Never Use Alone 1-800-484-3731Stays on the line and sends help if you stop responding.
- Full steps: what to do if it is already happeningOverdose signs, the recovery position, what to say on the call, and whether you can be charged for making it.
- Poison Control 1-800-222-1222Free and 24/7, for “is this bad?” before it becomes an emergency.
