Are their cocaine allergies???? SWM has been a casual user for 25 years, 1.5 grams twice a month, more in the summer. SWM lives in Vancouver Canada where free drug testing is available. Whenever SWM buys an ounce SWM has it tested and it always comes back with "no cuts or adulterants present' About a year ago after about .5 gram SWM's uvula would feel like it was coated with phlem, and SWM could spend up to an hour to clear it. Mouth wash and drinking water loosen it up and speed up the process. This has gotten progressively worse, and now SWM gets this reaction after 2 lines. It was very frustrating, and last night SWM thought SWM would try hooping it. It was all good, until after about .5 gram same thing!!!!! Its a long trip from SWM's ass to SWM's throat!!!! Anyone have any ideas as to what is causing this, SWM has searched the web for hours and found nothing
