Marijuana may indeed have positive effects, just as say wine is (apparently, a glass of wine helps the liver...or something). However, it is also deemed an intoxicant. As a general rule of thumb in Islam, all intoxicants are regarded as haram.
Some backing for this from the hadith:
The Messenger of Allah (Allah bless him & give him peace) said: ''Every intoxicant is prohibited.'' Sahih al-Bukhari, no. 4088)
''That which intoxicates in large quantities is prohibited in small quantities.''(Abu Dawud, Tirmidhi, Ibn Majah, and others, with a sound chain of narrators
Additionally, that which is haram is often harmful to oneself, others or society as a whole - that's a pretty good methodology, no?
Thus, Islam (and possibly religion as a whole, though I don't know enough about all the religions to be 100% sure about this) actually teaches you to keep control over one's own body - in all manners of speaking. In the long term, this translates into the betterment (and continuation) of society.
