I do wish you'd vape, instead, but I toked during both of my pregnancies and my kids came out so smart they didn't know what to do with them in kindergarten!

There are several studies on pregnancy and cannabis (click the link in my sig). In a Jamaican study, the kids of pot smokers were marginally ahead of "straight" mom's kids.

And from my own observations with other folks kids- pot doesn't mess up your kids ability to learn. The same cannot be said about the speed type drugs- I work in special ed- an amazing percentage of "my kids" have speed freak parents (some are now former users).

I have no clue where to find the answer to your question. Sorry. I wish you all the best.
