Yes, if you continue to do it everyday for a prolonged period. There are a number of positive and negative effects that daily marijuana smoking has on ones body.
Although this varies from person to person, as time progresses people will often report similar long-term effects.
Already some people here have mentioned the most obvious, being the strain on your lungs and respiratory system. It’s a fair enough to make a claim that any inhalation of foreign smoke and particles will cause harm to your respiratory system. But the question is, how do you smoke your weed? Do you use a high quality vaporizer? (the cleanest and healthiest method, also the most expensive) A water bong? This despite popular belief does not work as well as a filter as many people believe. (It does more cooling than filtration, which can prevent burning to lungs, throat, mouth) A Spliff, Joint, Blunt, glass pipe? (which offers little or no filtration at all.)
So it becomes more clear that a person smoking everyday, several times a day out of a vaporizer will most likely have healthier lungs than a person who smokes joints everyday, several times a day. Fair enough right?
But then there’s your mental health…
As a University Student in British Columbia, Canada. I can tell you that I am exposed to a lot of ‘daily smokers’ which range from every aspect of society. What I notice with those who smoke everyday begin to socialize less, suffer from mood swings, you start seeing them less frequently at social events, far less talkative (even when they are not high). These are clear indications of a daily smoker who abuses his right to smoke everyday.
I know this is a long answer to a short question, but I believe that giving a clear explanation is better than a short brief one which leaves even us with more questions.
If you smoke everyday, and don’t plan on stopping.Then treat it like it is a reward, don’t do it all the time. (eg. Smoking 20 bowls a day,or burning through a quarter (7g) in a day. Because if you do that it makes you no different than the crack heads, meth heads, and junkies living on the street, whose lives revolve around being high all the time.
Show the world that pot smoking can be a privilege, and something we can enjoy after a hard days work, treat it like having that nice beer at the end of the day. Your not drunk every waking moment of the day are you? Then why do you need to be stoned off your face all the time?
ps: I’m a daily smoker
