Yes... always for worse... i feel more irritated, more influenced by small things, sleep less, feel more energetic (what i, personally, dont like, as i feel anxious)... of course, my mind goes somewhat sharper after some days without smoking, but its the only good thing about it.
Yet, when i smoke i feel peaceful, relaxed, at ease with the world, happy... in short words, life is very damn good when stoned.
As the bad effects of not smoking are far greater than the good ones (for me), i smoke every day! :jointsmile::rastasmoke::stoned:
