FINALLY, a riveting book which thoroughly addresses every argument with a wealth of research! It was interesting and had a lot of common sense. At the end of the day, it's about the impact marijuana has on our young people. They have no business smoking marijuana when their brains are most vulnerable to permanent damage. This book was well worth the money. I think we've all heard the arguments and OPINIONS FOR legalization. If you're looking for a well-rounded and educational argument which addresses the medicinal benefits as well as the biological and societal consequences -THIS IS THE BOOK! I now understand how marijuana can be helpful to people who suffer from AIDS, Cancer, or Glaucoma -who TRULY NEED IT! I understand how the THC levels are higher than back in the 60's, etc. which is causing a higher chance of getting high and how the THC levels are not regulated which has caused lots of people who don't need it for medical reasons to abuse it for recreational reasons for the high. It's especially sad that young people are adopting this same attitude as reasons why they use it or don't see anything wrong with using it. This book opened up my eyes to get an understanding of both sides of the argument and has reinforced why I will not advocate legalization of marijuana for recreational use and if used for medical purposes the THC levels must be regulated. Much thanks to the Authors for sharing their passion in a society where it's not popular to speak up against legalization of marijuana.
