Tangential addendum: I used to smoke pot all the time. From my mid-teens to mid-twenties. At least once a day, increasing over time to 3-5-∞ times a day. In the last year, I have significantly reduced my marijuana usage to less than once a week. My mental health has benefitted tremendously (also thanks to a great therapist!). I sleep better, I eat less shitty food, I enjoy sex more, I feel overall more equipped to handle my daily life and be an adult. I only date people of the same sex, so standard reproduction isn't a big concern for me; but if you're a pothead like I was (am?)--there's a lot more to reflect on than your sperm count. :)
