Potheads, pill poppers, and other druggies (and believe me I've been them all at times in my life) will all tell you they do better at whatever they do when they're under the influence. That is flat out bullshit, a form of denial, and helps them justify why they are addicted. If you're in recovery, as I am, you get it. If your not in recovery you will justify anything. There is far too much evidence to support the fact that when you're under the influence of a mind altering substance, pot included, that you have a decreased ability to perform ANYTHING, versus someone who is not under the influence. If you think otherwise then your just another addict in denial. Plain and simple.
