Sports like basketball burn quite a lot of calories as it requires too much of physical exertion.
But to know exactly how much of the calories are burned while a specific physical activity is carried out somehow depends on the weight of the person and that how vigorously that person has been practicing it.
However, we can estimate about 500 - 700 calories to be burned in an one hour game of basketball.
I believe that teens to drugs is because of the people around them. They might do it because they're stressed, have anxiety or because of their friends. If they're with the wrong people at the wrong time they way feel pressure to do drugs.
