I would get some money to by weapons and gear before you start making money illegally. Start off with wreck excavating, it gets you a lot of money as a new player and youre pretty unlikely to get robbed. Once you have some cash for a decent gun, you can do illegal stuff. You have to protect yourself when doing drugs, doing it without a gun is just asking to get robbed, its just the nature of the game, we've all been there.
