One of my friends has a problem with a spouse prone to sudden rages, and since said spouse smokes a lot of weed, I started looking for information about a possible connection.
Spouse seems to fit the description of what they call “rapid cycling bipolar Type II” (previously I thought it might be hyperthyroidism, but the behavior sounds a lot closer to bipolar. Some researchers think the conditions are associated). Spouse is a lot more mellow after smoking, but “worse after it wears off.”
Turns out that at least some doctors think the weed might actually cause the manic/rage episodes, that it’s not immediately apparent because it takes a while for the pot to trigger the chemical cascade that results in the manic rage.
Since some bipolar people feel better when they smoke, they insist the pot is treating the disorder, not causing it, and that doctors are paid by the government to come up with reasons not to smoke.
Obviously, no one’s going to figure this all out anytime soon. Just thought it was interesting!
