I wouldn't use cannabis as a method to relieve depression. What goes up must come down. Get off all meds, tobacco, alcohol, caffeine etc. Drink water, eat well, sleep well, go to the gym for at least an hour or so a day. Once you are doing all the right things and still feel depressed get some tests done. It could be as simple as an allergic reaction of some kind, deficiency or maybe you are low in testosterone. Find hobbies that are fun, challenging and time consuming. Donā??t take meds just because the doctor prescribed them as a quick fix. Make sure you find out why you are depressed and then take the appropriate course of action to fix it.
I read about a study that was done where each control group were prescribed different things. 1 group was prescribed meds, 2nd group exercise and the 3rd was exercise and meds. The group that was prescribed exercise only had a better success rate than both the other groups. I think somewhere in the 90% range.
