Cannabis was once considered to be an illegal drug, but after many years of research, lawmakers in a number of states allowed the use of marijuana medicinally. As more time has passed, many of the states in the US have now passed legislation that legalizes the use of weed recreationally. This goes to show that there are no harms in using marijuana/weed.
If you happen to be a part of the population that has never tried cannabis and is now considering to start out, then you want to make sure that you start out safely, because a bad first experience can end up causing you to develop an aversion to something that is not really harmful.
The first thing you want to do is to look up dispensaries near your area, and you can easily find a number of San Diego cannabis shops around you that can meet your needs. When you go to a dispensary for the first time, it is better that you acknowledge your inexperience to the people there. People working dispensaries are more knowledgeable than other people regarding cannabis, and which strain and amount should be given to an amateur. This way you can be sure that the weed you are getting is not only safe but also something that will make your first time experience a pleasant one.
It is also recommended that you have a friend or someone you trust help you out and accompany you the first time you do smoke cannabis. This is to make sure that you are doing it correctly, and also to make sure that you are safe, and do not potentially hurt yourself the first time because the experience can make you a little light-headed and make it difficult to do simple tasks. Lastly, keep water with you and remember to have fun.
