I worked on a narcotics team for a bit.
There are different thresholds people have with addictions. Some people can try a drug once, and just never pick it up again, others can pick something up and be addicted. Ecstasy (not extacy
) is made with either Amphetamines or Methampetamines. the actual name is 3,4-Methylenedioxymethamphetamine (MDMA) or the same thing with Amphetamines (MDA).
Meth is a highly addictive chemical.
As a person who is highly educated in drugs, I'd just say, don't do them. But as a person, I know that isn't going to help. I'm sure you know that you never know who made the batch, what all is actually in the pill etc. For a while I was getting people who were getting pot laced with amphetamines and cocaine, as well as some with lsd. On top of that, it is a chemical. If not mixed correctly it could cause you to die. There are also long term effects.
In short, no the average person will not become addicted after one use. Only you know if you are addicted. Have you used it since? HAs your body gone through withdrawel symptoms? If the answer is no to both, then you are not addicted. If it is yes to one, seek help. Don't let drugs ruin you.
And about the alcohol, define a lot, how much you drink, etc.
