When it comes to drugs, I’m quite experienced, though I certainly wouldn’t consider myself a stoner. There are only a few I haven’t tried and never plan to (cocaine, heroin, meth, most opioids). These days I don’t get high more than four or five times a month. I occasionally give people advice on how to trip safely, and which drugs to avoid entirely. Part of that is a very strong recommendation for people to NEVER abuse prescription drugs of any sort, for any reason. Well, here’s a big part of why I do that.
Not many people are aware of this, but Viagra (sildenafil citrate) was first invented to treat high blood pressure and sold under the brand name of Revatio, which it still is today. The men who took it noticed a nifty little side effect, and two years later, Pfizer manufactured a bunch more and sold it under the brand name of Viagra, to treat erectile dysfunction. Chemically, it was no different than Revatio, except the pill was blue instead of orange.
