Mixing Amphetamines and Methamphetamine
- Amphetamines also called
- adderall, speed, amphetamine, dexedrine, vyvanse, lisdexamfetamine
- Methamphetamine also called
- meth, crystal, crystal meth, ice, tina, shard
Caution
Roughly the same molecule doing the same thing, so this is mostly a redose question wearing a combination's clothes. Methamphetamine is about twice as potent and lasts 8-24 hours against amphetamine's 4-6, so adding prescription stimulant to a meth session extends cardiovascular strain well past where either drug's effects are still worth having.
The risk here is to the body — breathing, heart, temperature or organs. Set limits before you start, because this kind of harm does not announce itself in time to react.
