>>Dr Burns says while any drug use during pregnancy can be harmful to the unborn child, the effect of cannabis smoking has previously been down-played. <<
This article does a very good job of downplaying it further. Unless I am missing something here, the only negatives they found was the possibility of premature and lower birthrate but, even then, gave no statistics. Was it a 1% chance, a 90% chance? Who knows.
This article is the type of stuff I read in the 1970's. It is just poor. It is also sad because I simply cannot believe that grass is really that benign.
Oops. Birthrate=birth weight.
Well, at least it rhymed with birth weight.
