I don't suggest getting high for depression, but there are a few legal alternatives. None really as good as weed, sorry.
1. Nutmeg, it sucks you might not like it, but the high is "somewhat" similar to weed.
2. Poppy seed tea, might not work because it includes morphine which can take a few days to get out of your system. If you want to do it get around 300+ grams of poppy seeds, grind them up and leave them in room temp water over night.
3. There are legal buds and shit, look around. I've heard of kava kava and kramton being effective. Try
www.iamshaman.com or something there are a bunch of legal drugs. Try amantias maybe.
4. Drinking works.
There are other legal
drugs like morning glory seeds, cough syrup, salvia etc. I don't suggest those because really if you're depressed hallucinogens may not do anything to help.
