The decision-making part of the brain of an individual who has been using crystal meth is very interesting. When Carly and Andy were in their apartment, they ran out of drugs. They sold every single thing they had except two things: a couch and a blow torch. They had to make a decision because something had to be sold to buy more drugs. A normal person would automatically think, Sell the blow torch. But Andy and Carly sat on the couch, looking at the couch and looking at the blow torch, and the choice brought intense confusion. The couch? The blow torch? I mean, we may not need the blow torch today, but what about tomorrow? If we sell the couch, we can still sit wherever we want. But the blow torch? A blow torch is a very specific item. If you’re doing a project and you need a blow torch, you can’t substitute something else for it. You would have to have a blow torch, right? In the end, they sold the couch.
