dont buy anything yet. first of all weed isnt for everyone. I like the stuff and smoke daily but i have plenty of friends who dont like it and dont smoke.... dont do it just to do it try it if you are curious. Second if you are going to try it then just ask your friends who smoke and smoke with them. stoners are generally very welcoming people. Finally I know this is going to sound like bs but make sure you have your priorities straight. Smoke as much as you want but dont fuck up school, family life, or your friends because of it. At the end of the day i have seen people change from smoking weed and really fuck up with it but i also know pleanty of people who smoke all the time and have kept their shit together. Weed isnt bad I think it is good but I do think heavy use can have negative effects on people. Finally, don't jump straight to buying stuff. Try it a few times and see if you like it. You might or you might not. Best of luck
