Mixing Amphetamines and GHB / GBL

Mixing Amphetamines and GHB / GBL calls for caution — TripSit rates this combination “Caution.” Low risk never means safe.

Stimulants increase respiration rate allowing for a higher dose of sedatives. If the stimulant wears off first then the opiate may overcome the individual and cause respiratory arrest.

Amphetamines (also known as Adderall, speed, meth) and GHB / GBL (also known as G).

What to do

• Even for lower-risk pairs, the safest choice is not to mix — and never to use alone.
• Start with much less than usual and go slow — you can always take more, never less.
• Never use alone. If you do, call 1-800-484-3731 (Never Use Alone) so someone can send help if you stop responding.
