Goomba.... MAYBE it is bad for your lungs (who really knows... the smoke tastes good and is smooth), but I do it quite often and I've never had any problems.... the smoke tastes sweet and it DOES serve a purpose. Dont listen to these idiots talking about "wasting"... It is one of the fastest roas for hitting your brain, so you get a relaxing rush instantly and it is fun to do once in awhile.
One concept, for instance, is that if you use a hose clamp to grind ur pills for snorting, u will be left with these tiny little flat pieces of OC that are super hard to break down and like 3-4mg, and I almost always smoke them--- they are perfect for that. if u snort a small piece you wont feel it cuz snorting spreads your high out longer than smoke, so smoking u can get a fun little rush that although is short lived, potent considering the small amount u did-- even if in the "long run" snorting would have been technically more effective (IE (random example) 5mg-- 90% absorbtion spread over 3 hour high, or 75% absorbtion concentrated in a 20-30 minute high).
Smoking isnt as good as a MAIN ROA--- I'd suggest snorting or parachuting to get your main base line high going, but it is really fun to smoke because u can smoke VERY small pieces, get a lot of smoke, and have fun with a little OC rush here and there during ur opiation.
If you are in W/D, also, you can take your finger nail and break off the smallest piece of OC, smoke it, and feel yourself get instant relief from W/D. Its awesome. I would never put like 20mg or more on tinfoil.... just use it to adjust your high and enjoy a little rush while you use other methods to get high.
