I wonder about that too. But we're trying to reason this out from a position of "sober" or at the very least "not on crack/hardcore stimulants". You ever know a crackhead or meth head? I have. They go on benders, and these drugs are "uppers" so they make you feel really confident and full of energy. However, with prolonged use, your brain chemistry gets all fucked up. You take that first hit of crack, and your brain dumps out a shit ton of endorphines and dopamine that it had stored up. You keep going, and eventually your brain is so saturated with dopamine, you become delusional and may end up with a condition known as "amphetamine psychosis". Essentially, the person becomes schizophrenic until they crash and sober up. Sometimes, the effects can linger. He probably feels okay doing this on video because the drug makes you feel fucking invincible. And throughout his entire life, he's never had to face any consequences, because daddy Joe has all the connections. He can smoke crack on camera, dozens of times, he can be nude in photos with young girls wandering around... he can do whatever the hell he wants, and until Americans say "we're not tolerating this fucking loser or his tyrant father anymore", he's going to continue to get away with this shit.
