Well your teenager has found a new toy to use. Many teens have been smoking Hookah because they believe that it is safer than cigarettes or marijuana. Unfortunately they are wrong. It is just as dangerous and might be more dangerous.
Smoking Hookah is a group activity that is common in the Middle East and India. Since it is a group activity, it is appealing to teens. Also since many adults here in the United States know little about it, this makes it more appealing to teens because it is easier to lie about. If you look up Hookah, you will find there are numerous places that teens can go in Pleasant Hill, Walnut Creek and Concord to buy a Hookah pipe and Hookah to smoke. There are also Hookah cafes similar to Starbucks where teens can go and smoke it. And now finally there is the Hookah pen. It looks like a regular pen so they can take it any where such as school and smoke.
However, the Hookah pipe can be used for smoking more than Hookah. The teens are combining Hookah with marijuana to get high. Now that there is a Hookah pen, or vaprorizer pen, teens can easily take this to school and smoke during class. As a parent you may want to discuss Hookah with your teen and see what they know or don't know. You may want to discuss the pros and cons too. Also remind them if they get caught with the pen on campus, they are in trouble.
One thing this should point out to parents is that you should never let your your guard down. Teens are always developing new ways and new devices to get high. Check out this video on YouTube to learn more about these pens.
