Beware – you really need to read this! Smoking marijuana can have long term adverse impacts on your brain. If marijuana is smoked at least once per week, the effects can be long term (which means they can last up to one year). Some side effects may include delusions, anxiety, addiction, depression, and lack of concentration, memory loss, paranoia, and much more. Drug abuse has negative impacts on the brain, but the long term effects that linger on must be considered also. Chronic abuse of marijuana (smoking several times each day) may risk your health, social life, and economic stability you need to ask yourself is it worth the risk? No! Absolutely not! You need to consider the negative implications if you continue to smoke marijuana.
