do you mean, "Are you doing something wrong if you DON'T see any smoke when you exhale" The answer to that question is clearly yes. if there's no smoke, there is no smoking. this would be a fairly futile method of getting high (unless your vaping but i doubt it).
Well I usually hold it in for about 20-30 seconds and rarely see smoke when I exhale. If I hold it for ten I see plenty of smoke. I seem get high better/faster holding it in till I cant see smoke when I exhale. Just curious. On a side note I got desperate and tried smoking ceeds/stems today and found out why everyone says DONT DO IT
that's called a "ghost hit" it gets you pretty fucked up, but might not be very good for your lungs. the thc will evaporate into your lungs in about 5-10 seconds, so anything passed that is just lacking your brain of oxygen. and making you feel 'higher'
I find when I take ghost hits I end up burping out smoke (or it tastes like smoke), which is gross for me, and especially bad if I'm hanging out with non-smoking friends, so I usually try to avoid it. Plus, like 40oz said, I don't think ghost hits get you much extra thc.
^ haha yah once at work I was smoking and had to take care of a customer and burped out smoke in front of him. I just acted like it didnt even happen
yea i used to do that back when i was young and stupid but holding it in 10 seconds does nothing more or better compared to 30 seconds. all the smoke just dissapates in your lungs before you exhale so no you dont have to worry about doing anything wrong.
You don't need to hold it that long... A few seconds is plenty. I hold my hits in for about 3 seconds and I get just as high as when I used to hold them in as long as I could (When I didn't know any better).
I was just curious one day so I noticed that when I hold it down in my lungs for a while it comes out not as visible, but when I barely hold it in you can see it pretty good. After a while though especially in a car you barely notice anymore because its so smokey.
I guess it doesn't help I usually drink a 370ml bottle of vodka before smoking. So 5 seconds sounds good.
You only need to hold it in for ~10seconds. You are doing nothing wrong if you don't see visible smoke after holding it for a while, as pointed out, that's a 'ghost hit.' To make sure you're smoking right, you can take a hit, hold it for 5-10seconds, then exhale thru your nose. Smoke should come out.
