• New medical guidelines have been issued in Canada, where cannabis is legal
  • They warn the effects of the drug outweigh minor benefits for most conditions 
  • And for some, it states it most often is only marginally better than a placebo 
  • The new document will be distributed to 30,000 doctors in Canada

The document, published in the Canadian Family Physician journal, warns doctors to 'take a sober second thought' before prescribing the drug.
