I think you're very wise and that this is a good way to go about life, research fully any drugs you plan to take before you take them. Two months really isn't a long time and may as well be waited. Just consider that smoking isn't like anything you've ever read. The effects are usually a lot milder than new comers expect them to be, you'll probably end up smoking fuck loads though, if you're planning on growing, that'll be fun won't it
