I take 54 mg of concerta everyday because I have really severe ADD (I'm a skinny 16 year old girl) I just started smoking weed regularly like 2 months ago; as in 2 or 3 times a week, and when I smoke on days that I've taken my medication aka a week day I get a super weird high that's like the world is sort of pulsating and spinning it's hard to walk/ stand like it's cool but it's freaky too. When I smoke on a weekend that I don't have homework or anything that needs to get done or whatever so I haven't taken my medication I hardly get high compared to the high while I'm on medication. Idk if I'm crazy or if anyone else has the same situation !?
