Most people I meet think that cannabis is bad. This is not right but it's not wrong, it's down to opinion, and my opinion is that it can be integrated into your lifestyle creating a much mellower you. the positives; you get more sleep, find yourself being more relaxed, and if you associate with a group of people who also enjoy cannabis you can find your self having many interesting conversations. Conversations about physics, politics, the Environment...and many more fascinating topics. Listening to music as possibly the best thing that you can do while stoned. Like everything that I enjoy there is always down sides, these are different depending on the individual. Some people become paranoid, this will mainly be due to your state of mind, and how you use it. If you are using is as an escape from all the work/requirements of life then you will probably self-destruct because it tend to make people lazy/lazier. Over all though as long as you are still leading a well structured life and have time and money to spend on Marijuana then go for it, open your mind and share the love.
