If you experience unexpected or concerning effects from GHB or GBL you can notify High Alert to help keep others safe.

A Reddit user gives their advice to people looking to take GHB:

“It’s addictive, destructive, and extremely easy to overdose with. It’s nearly killed me on more than one occasion involving my bad choices. If you decide to use it, just remember it deserves great respect. Inform yourself about dosages, interactions, and I remember to always set a timer when I dose. When you’re high on this stuff, you have no concept of time at all, and it’s super easy to double dose and never even think about it. A double dose can put you in the hospital. Also remember no alcohol at all. Don’t let anyone talk you into drinking with it. Just be safe.”

GHB and GBL can be very easy to overdose on because there is a small difference between a common dose and a dangerous dose. Visit tripsit for more information on dosing GHB and GBL.
