Whatever. Nonetheless whatever ROA you use, you eventually end up with terrible anxiety at best if not with worse mental disorder like stimulant psychosis. And these downsides of use only concern state of mind. Stimulants also wreck you body. I mean, take a tobacco smoker with 5-year addiction (~20 cigarettes a day), take a person addicted to pharmaceutical grade opioids for 5 years, well, you can even take a heroinist who's shot up brown heroin for 5-years... And compare them with someone who has used amphetamine (we'll see similar cases with mephedrone soon). I guarantee that a person who doesn't know anything about drugs a) won't recognize a tobacco smoker unless (s)he could smell smoke, b) won't see any outside signs of opioid use in a heroinists, and c) will certainly notice problems with teeth, skin, hair etc. in the person addicted to amphetamine (or any similar stimulant).
