Marijuana is know to make people lazy and immobile. I have a different theory on this idea.
I feel like marijuana only brings out the true laziness in a person, it does not make a person lazy. This stereotype has been attached to marijuana for a long time. It is true to an extent. Everyone likes to have lazy time if they smoke or not. What if many pot heads like to smoke and be lazy on their free time? That sounds logical to me.
There is such a thing as the functioning pot head. A countless number of people do regular daily activities while they are high. Not every person who smokes marijuana is lazy. Many people enjoy doing anything high, even homework for school.
It all depends on the individuals motivational level. If a person was destined to be lazy then that person will be extra lazy. If a person is motivated and determined then they will enjoy all of their daily activities even more because they are high.
An individual digs their own hole they bury themselves in because of lack of will power and self-restraint. No one is to blame, except the individual, for letting themselves wither away into nothing but a pot head. I am a pot head so I can say this, but I am a functioning pot head and there is a line drawn between the two.
You can't blame the "drug"for certain peoples inability to function as more than just an instinct based creature.
