I smoke pot. Maybe 1 hit a day if I smoke at all. Would that cause cataracts??

Very little data. There is very little data about the relationship between smoking cannabis and the development of cataracts. Smoking anything at all is not good for you (because of the particulate matter), and cannabis certainly has other ill health effects (COPD, lung and oral cancer, development of breasts (gynecomastia) in men), and some health benefits. Cataracts are not among either.
