Is Autism linked to Birth Trauma?

I've got my own theory on this - as usual ! .....and I think it might be something to do with smoking - I'm sure my mum smoked when she was pregnant with me - another thing she did was give me sleeping tablets when I was very young, she denies this but I used to have very traumatic hallucinations sometimes inthe middle of the night and years later when I read about giving sleeping tablets to children it rang a bell, I asked my mum about this and she denied it and said she has never given any of us sleeping tablets but I absolutely 100% remember her giving my younger sister a sleeping tablet and I remember her clearly talking about giving a sleeping tablet to my sister and she was very young then, still in a pushchair so probably about 3 years old. I had awful hallucinations who knows what it did to my young brain.
