RG,

There are similarities to what you describe of your H and other addictions. Not trying to scare you just similarity. Smoking typically starts with "I'll just try it." or " I didn't think I would like it." etc... Here is an atricle about the release of natural chemicals (endorphines) that are typical with any type of addiction.

Take a look and see if you think the logic applies.

Have you visited the other sites? Did you find similarity? There is a ton of info there, let us know what you uncover.
