vaporizer dose help but it sill can cause some tightness in the chest depending on the amount and the type of bud i am concerned that micro dust gets inhaled. i quit the cigs n only have a total of maybe .1 or .2 g's a day but it still fucks with my breathing the problem is chronic so i have resulted to eating it and it still causes tightness so i am wondering if it could be some type of allergy maybe or could there be some kinda contaminants in the bud causing this reaction
