Sharon Stone was as "sick as a dog" for months after she gave up cannabis and stopped taking her stroke medication. I’m like: 'I’m going off it,' and it was like going off of f****** heroin. Sharon also resolved to giving up cannabis and that also made her ill. She added: "Once I got off that [the stroke medication], I decided I’m going to quit smoking pot. I went to my neurologist, and he said: 'Sharon, I’ve had people dying in the emergency room from marijuana'." "When I reconsidered what value things had to me in life, I really wanted to have children and spend my time with them.
