I hate to break it to you, but when you see videos of them rapping and they've got "booty girls", expensive cars, planes, and houses, that's all fake too in the vast majority of cases. The houses, cars, and planes are rented, the girls are hired for the shoot, and most of their jewelry is fake.
A lot of rappers come from the ghetto where they DO smoke weed, and may pimp girls on a small-time basis, and they may get away with it for a while because the police are so overwhelmed with bigger crimes (murders, kidnappings/missing people, etc.) to spend time on that on a regular basis. But lots of things that aren't strongly enforced "in the hood" will get cracked down on QUICK in suburbia.
And people from ghetto cultures think that "respect" comes from defying the law and collecting "stuff" that they couldn't afford in the ghetto, so it's no surprise that rap songs are full of that stuff, but as I pointed out earlier, most of it is fake, and just used to create an "image" of success.
Only a fool would take what he sees and hears in the media at face value, because so much of what you see is fake. You only see and hear what they want you to see and hear.
