I don't wan't to be mean, but I hope you created code names, because I'd kill you if I were this Jessica >.<
Well but yah, drug use is not good... Unless you use it to relieve pain, then it's ok...
The thing is, drug use brings you short term pleasure and when that short term passes you either need a stronger drug or, if there is none, you shall never feel happy again...
My mother worked in an organisation that helped drug users and she drew us a graph... It looked a bit like the world temperature graphs you see around, only turned around- when you first use a drug, you get really high from it. It feels so good, you need to try it agan, but, when you do, it will feel less nice, still you'll try again, and each time you do, your pleasure from it falls, and then your alltogether pleasure levels fall bellow normal, and you can't get this pleasure tick back up like you can get the world temperatures back down... Sooner or later you'll end up one damn of a depressed person.
I saw that happen to my grandpa, though he was using tge drugs to relieve pain. When he used those things... he looked really bad, really sad, couldn't walk very well, he looked half dead.. and it had happenned only in a few weeks!!! And he kept on asking for those pills... We gave him weaker ones and he got better.. but he never was the same... so yah...
Of course there are some people who don't get addicted to druggs, but those are rare occasions. Addiction is not good.. gets u sad sad

duntwant to see that happen to any of my friends... and happily, none of my friends ever use any drug...
