If someone's life is bad enough that they smoke, making them feel bad isn't going to improve things.
You don't have to smoke tobacco to feel good. Just go with good old fashioned reefer.
Ability to treat the two interchangeably is dependent on lifestyle and structure. If you're trying to be productive at 2 AM, better to not be useless.
Yeah like seriously, coming from someone who smokes both weed and cigarettes (far less than I used to), they really aren't the same thing. Marijuana only impedes my ability to get sh*t done, whereas cigs help immensely. Thankfully though I've mostly replaced tobacco with the vape train, and don't feel the urge for a cigarette nearly as often.
