Does weed do this too?

[Euphoric]

You're right for the most part. Marijuana can cause depression, which in turn can cause a person to lose 75%-100% (rough estimate, severity of depression is a considerable variable) of emotional and cognitive activity, thus making an illusion in your head that the only thing that can make you "normal" is to smoke a joint...or snort a line.

I highly doubt the accuracy of the above statement. Where did you read this??
Cannabis is not to be compared to the physical addiction potential of cocaine
In fact cannabis is an antidepressant
