Don't want to come off as bragging so I'll just stick to the facts. I started using drugs including alcohol when I started university (studying chemistry to be exact). I used cannabis and psychedelics once a week for half a year. After that I started drinking pretty heavily to the point that most days at the uni I'd be hungover. That lasted about 2 years I guess. Then I started doing codeine to stop drinking, which worked. Got dependent on that, another roughly 3 years of heavy dependency - most times I'd need a morning dose to even get out of the house. My GPA had been 5.0 (only A's) and I finished my diploma with honours. Currently I work as a chemistry teacher, but I plan on resuming my research in organic chemistry this summer. I'm still using drugs daily, mostly dissociatives, psychedelics, and alcohol. Codeine is making a comeback in the pharmacies soon, so I'm probably going to at least revisit that.
