Yes, exactly. Heroin is extremely cheep in Albuquerque not in the US as a whole. Price has come down in the last few years, since the Taliban lost their total control over Afghanistan (Whatever else they did, they kept Afghanistan out of opium production) but it's not a cheep drug. Except in Albuquerque. The city is also crawling with heroin distributors.

Actually, the ease of manufacture is why I couldn't buy Mary's sister smuggling meth to New Jersey like I could heroin. Meth can be made anywhere. There's no reason to lug it cross country. Heroin can't.
