Second hand pot smoke is just as dangerous as marijuana ingestion with the added detrimental effect of smoke inhalation (just as with cigarette smoke). If a dog is exposed to heavy marijuana smoke he can suffer marijuana toxicity which can make the dog seriously ill requiring veterinary care. Signs would be lethargy, ataxia, tachycardia or bradycardia and possibly organ damage. Please do not expose Chance to marijuana smoke.
