Democratic Sen. Tick Segerblom is sponsoring the bill that was introduced Tuesday.
SB372 calls on state officials to issue medical marijuana cards for animals if the animal's owner is a Nevada resident and a veterinarian certifies that the animal has an illness that might be alleviated by marijuana.
Segerblom says the provision is part of a larger bill that cleans up the state's medical marijuana statute.
Sen. Mark Manendo, a fellow Democrat and animal rights advocate, says he's concerned that marijuana might not be a safe treatment for sick animals.
Segerblom says he's also concerned that marijuana might have adverse effects on animals, but he says veterinarians won't know unless they try.
