It depends on who you ask DJam. In my opinion, frequent drug use is a healthy alternative to frequent alchohol and cigarette use. When you were a kid, your parents told you what to do probably. That probably included not taking drugs. Now as an adult its your choise on any matter whatsoever. I would suggest if you are keen to try drugs, begin with marijuana. people you meet who use marijuana a LOT (like me) you will find can link you to where to get to almost any drug, and also offer advise on which ones to take. personally i am very choosy with what drugs i take. Ultimatly it is your choise, and usually my choise is based on wheather or not the drug is addictive, unhealthy <( suprizingly weed is not unhealthy http://paranoia.lycaeum.org/marijuana/facts/mj-health-mythology.html )> and if i can live a maintainable lifestyle. Things i brush aside is: authority figures' opinions, legal obligation, and generally people who I dont like. OF course, it is also your choise to not do drugs. I am not trying to convince you to try drugs, just saying that its your choise and millions of people live peaceful, sustainable lifestyles whilst taking drugs recreationally.

Yes

I think it IS a personal decision. Just like deciding what you wear, or whether you eat fatty foods, or do rolling stops at stop signs. However, I think you should be at least age 18, because the physical brain is still developing before that and sometimes decisions are made hastily or not based on sound reasoning earlier.
