Marijuana could harm an unsuspected member of the family, pets.
Marijuana affects dogs differently than humans — it's toxic and could be fatal in large doses. If people aren't careful, pets could get a hold of weed edibles, such as brownies and candy.
The effects that might make a pot brownie enjoyable for a human can make a dog incapable of basic functions. In rare cases, a dog can undergo gradual paralysis and die. Fatal cases are rare.
On the other hand, there are some medical marijuana products that are specifically designed for animals that don't have a high presence of THC.
It can help pets that have chronic pain and mood disorders.
