Like you've mentioned, you have access to a lot of potentially lethal drugs that may lead to a blissful overdose. The only concern is actually getting caught and receiving felony charges. Then you go to prison and have to deal with prison culture and gangs for possible years. It will postpone your plans. If you plan on smuggling some of those narcotics, I guess be quick and sly. The more you steal from the same place, the bigger chances of you being caught. I've heard of people before getting access to narcotics because they worked at a pharmacy so this isn't too far of a stretch. It's your choice at the end of day so be wise with what you're about to do.
