Edibles are the smart, responcible way to go.
Sometimes people need immediate effect though, they don't have time to play around with the dose in their stomach, they're not using it to get high. These people should just avoid smoke getting in peoples face.
Even if weed is not usually deadly, the fear of weed, or co-administered drugs can be deadly.
If someone doesn't want to drink, don't make them drink, if someone doesn't want to smoke weed, don't make them do it. Even someone who is not a doctor can recognize that the individual might have more of an insight about their health than theyou do.
