For sure I would choose weed. The reason is that you can have fun on it, abuse it if you will, and you don't get bad side effects. Take alcohol for instance to get a really good buzz going you're gonna have some discomfort the next day. Use speed for a while and you'll be really unfortable. weed just is the nicest of these drugs.
my 2 cents

I'm also hoping that nicotine wouldn't be included because I have to have my newports to go with the heroin...gotta love burning yourself while nodding out.
Meth, crystal MDMA, Ketamine and weed
really good herb
