I don't have time to get a reply but if he's not my guess is that he's not smoking right.

I had the same problem. You only get high when THC and other canabaniods are absorbed in your lungs. Most novice smokers only fill their mouths and windpipes with smoke then cough it all back up.

When you are not used to it and your body is going nuts trying to reject the smoke your windpipe can feel youâ??re "breathing really deep".

My suggestion is to have him suck on a cough drop while he smokes (hold it under your tong to keep from inhaling it). It should help suppress the cough reflex.

That's what helped me.
