The US military used to issue speed to pilots & special forces to keep them sharp.Probably still do.
But the current stuff sounds scary. My younger son had a couple of mates a while back who used meth.( and steroids). Nobody would want to upset them. Whereas the stuff 40+ years back just kept you sharp & confident and wasnt addictive (except maybe psychologically). Coke? Never tried it. Saving that for when the family chucks me into a nursing home in years to come.......
