Does it really work? I smoke quite a bit and find my tolerance quite irritating. I'd love you forever if this works.

To the original guy: Just stop smoking for a few days and if that doesn't work, stop for longer...obviously. Be sure not to abuse it, investigate your highs and what you enjoy about them, don't just go about it passively. This is the psychological aspect that could be affecting your high. Either way, abstaining for a little while is almost certainly going to be beneficial.
