i had and aerious cortison pil 5 mg ,just a few minutes ago .its 13:00 o clock now. also in the morning i had a 250 cortison injection on my buttchick in 6:45 in the morning . alla that because of an alergic reaction to pine trees. i could breath and see it wasnt so rough but the thing was that i was fully itchy (like more than 200 mosquitos bite me, that was rough ). i m about to take 2 more pills an use a fenistil cream for the rest of the day. does marijuanna do any harm if i smoke it. ??
