I wasn’t talking about methamphetamine specifically. Amphetamine and methylphenidate are regularly prescribed for daily use. We know them to be relatively safe in sensible doses. Cocaine destroys your heart and your nose. Lookup any ranking of drug danger, cocaine is up there with meth and alcohol. It’s one of the most addictive too.
If you’re doing that much daily you need to see a doctor and get addiction counselling. Legitimately please get help before you do yourself serious damage. Unless you’re talking about coca tea of course in which case carry on. I don’t think that’s you though.
There’s also no such thing as pure cocaine in western counties pretty much. Unless you live where it’s produced you aren’t getting a pure product. Even then I would be skeptical if you know anything about the people who produce it. Go get your stuff tested at a lab if you don’t believe me.
