Ritaline is one of the greatest drugs on earth. If used properly. Not to brainwash kids. If you get really WASTED on weed, and then do ritalin, its like being right stoned out of your mind but being able to consentrate and hide the fact that your stoned out of your mind at the same time. It makes you feel so good! It also has an effect like speed, gives you tones and tones of energy and helps you stay up all night. Even if you have A.D.D or A.D.H.D, because I have A.D.D, I sniff it or parachutte 2-3 pills every few hours. It does what its perscribed for to, it makes you able to do anything! You consentrate some good but it makes you hyper as hell if you do lots!
