Hi, my name is Sara Bellum. Welcome to my magazine series exploring the
brain's response to drugs. In this issue, we'll investigate the fascinating
facts about marijuana. Some of this information was only recently discovered
by leading scientists.
You may have heard it called pot, weed, grass, ganja or skunk, but marijuana
by any other name is still a drug that affects the brain.
Did you know marijuana can cause some people to lose focus on events
around them? It makes others more aware of their physical sensations,
and it has still more effects on other people.
All these different changes are caused by chemicals that affect the
brain. More than 400 chemicals are in the average marijuana plant. When
smoked, heat produces even more of them!
