Why did you think that was a good idea?
Judging by your stupidity you probably already suffer from lead poisoning.
The human body also confuses lead with calcium so whatever lead you get in your body will build up and stay there for your whole life.

Have a read on lead poisoning and decide if it's worth smoking contaminated plants.
I can give you a hint, it's not worth it.
Throw that shit away, lead isn't something you want in your body
