Rick's weed *was* laced

So in the most recent episode when Rick is asked why he let the snakes out. He says he thinks the weed was laced (with other drugs). This sounds like a BS excuse, but after rewatching the episode. I think he was telling the truth.

I myself am a veteran smoker, and even with his reduced tolerance of going a few days without it, his reaction to the drug did not seem usual to me. He seemed impulsive. He seemed to lack inhibition, he seemed anxious, he seemed wound up, he seemed to not think critically or logically about his own safety. He seemed compelled by his inner spirit, He did not seem hungry, or relaxed, or humored.

His drug reaction was way more in line with my experiences with hallucinogens like Mushrooms. Which to my knowledge cant be smoked. LSD is too long lasting for it to be that. I don't have any experience with the other ones, but I do know peyote and PCP are 2 of the more popular drugs to lace weed with (which btw. Is not really as common as you think, I've smoked over a decade and never gotten laced weed before)

Anyway I'm aware this probably will not end up mattering at all. But I do think it kinda informs us a little about Rick, in the sense that he is more honest than he sounds/seems.
