So it was Illegal?
Sure sounds like it. IMO it's just a continuation of his "thrill-seeking" behavior, which I attribute to someone being dead inside. Anything to feel something?
It's reckless and irresponsible behavior if you're a single person, but when you have a family? Well, he's already shown his disdain for them, so no surprise he doesn't put his responsibility toward them high on his list, certainly not above "things that might make Lloyd feel good".
He's on the path now, he'll grow bored as the current experiences becomes numb, and move on to something more "exciting" and as long as there's a helpful pusher ready to give him his first hit for free, he'll be keen to accept the offer.
