This article discusses human brain development and what is known about the effects of exposure to cannabis to it. It summarizes the differences between traditional uses of cannabis and more recent uses as a drug rather than in a social context and their possible health implications. It discusses the Farm Bill’s provisions on hemp. The next article in the series will discuss the risk in the use of cannabis in food.
