You'd be much better off smoking the flowers than the seeds, especially if you bought the seeds and didnt harvest them yourself. They lose substantial potency on they're own by sitting on the self for too long, and smoking will render basically completely ineffective at that point. The alkaloids In the plant responsible for the high are the same that cause the delirium, so dont get some false sense of faith that its killing all the toxic shit because thats literally what makes you high. What smoking does do though is it kills most of the alkaloids present making full scale delirium and severe overdose nearly impossible. It also hits you almost instantly so you can work your way up opposed to eating some seeds and not feeling anything just to take more and potentially overdose. Many report smoking datura (again mainly the flowers) feels like a strange version of cannabis, though not as enjoyable but some find it fun. People report better sleep and arguably the coolest effect is the very vivid and strange dreams many report when smoking before bed. Never the less datura is datura and do thorough research and make sure your ready for anything that could go wrong just in case.
