Totally agree with what is directly above about addiction and abuse. Anything that is pleasurable has the potential abuse.
I view it exactly the same as alcohol. A certain percentage will be addicted, and it will cause them issues in life. Maybe it is our age group, but we meet very few 50 yr old "potheads" in the lifestyle. I really don't see the difference between the person that drinks a couple of glasses of wine in the evening vs taking a couple tokes. We have sat in a hot tub smoking a joint a police officer and a lawyer at a recent party. Most of the (vanilla) users we do know are professionals, have good jobs, kids, and are generally quite successful in life.
I do a have one vanilla friend that have been smoking weed all day, everyday for many years. I would say he is completely addicted, so I know it can be a problem. I also have friends that have destroyed their life with alcohol, sex addiction, and a myriad of other addictions. Moderation is key to everything.
Me and my wife are very occasional users, a gram lasts us a month, even when we share it with our friends. If a couple is not 420 friendly, it isn't a big deal. If they are, we will smoke or vape some with them. We do tend to have more fun with those who are.
I fully agree with trying 2 separate profiles. We do have 2 separate profiles and it does attracts 2 different sets of people. We get far more meets from the profile where we are 420 friendly. Even then, the people we meet do take very good care of their body and are far from addicts. In our area there are ~20M people in a 30 mile radius, and pot is 100% legal. Our biggest issue is finding time to meet people. Even if we put off 50% of the couples, there are still hundreds close by that are not put off by it.
