I also use the O-Pen. I believe there used to be a special on them in CO. Go to there website or, I believe, the site that manufactures the cartridges for them. The deal may still be there.

I have seen these, however I thought they took a liquid that takes the place of smoke and delivers nicotine. I must be really behind in tecky stuff. How does this work with MM? We do not have access to this is Florida. The pens yes for the nicotine, but never heard of how you use it with this Penvape. Oil? I am not sure that is anywhere to be found in this illegal state. That is why I am on the trail for signatures. PM me please, and I will give you my e-mail. I would like to know more about this. Does it remove THC? Isn't that the substance that doctors test you for? I am sick to death of taking pills, In fact so much so, that I jumped into this fight in our state, risking my own reputation in my community. ( I was involved with my city, and a rescue agency). In time, pills do not work, and then you have to go up on the dose. I am absolutely refusing to do that. Sick sick sick of pills.....ginnie

I knew what TCH was, and what the pen is, I just didn't know it is used with Medical M, or how? Plant in the chamber?, I would have no idea...... If it is an oil, I guess I have to wait until it is legal in my state. Not available to my knowledge, nor legal to send out of state for. Never knew this pen was used for MM at all. My son used the pen to re-place that old pack of smoke habbit. That was all I really knew about this subject. ginnie

Less damaging than WHAT? They're not the same as a plant material only vaporizer. A plant material only vaporizer heats dried marijuana and nothing else; vape pens/e-cigarettes, OTOH, require some kind of liquid in the cartridge. What is that liquid that people are breathing into their lungs, and what proof is there as to what damage that liquid may/may not be doing?

I'm sorry, but the statement that they have NO smell is blatently false. From the website itself:
I also take exception to their claim that:

When I wrote that, I was sitting at a table of 10 people at which one was "vaping" and made the same statement about lack of odor. Out of those 10 people, the only ones who said they didn't smell anything were the vap-er and one other person who was also a vaper; everyone else could definitely smell it—some as far as ten feet away.

If you can smell it, you're breathing in whatever is being put out by it, which includes any drug/medication and any other secondhand by-products, whose safety has not been determined.

Please note the weasel words that the marketers use: less does not mean none, cleaner does not mean clean, healthier does not mean healthy, and safer does not mean safe.

E-cigarettes: Does smokeless mean harmless?

How Safe Are Electronic Cigarettes? Not Everyone Agrees

Which delivery method one chooses for medical marijuana is a personal choice, but lets not deceive/delude ourselves into believing marketing hype that these vape pens or e-cigs are "safe" (risk-free) and don't expose others to whatever chemicals are being inhaled.

I was diagnosed with fibromyalgia in 1996. I learned about people using it for fibro in 1998. I have been using it since with very good results. It helps with relaxing my muscles and eases some of the pain. I don't know why the federal government doesn't just let it go! They have been fighting legalization for years. What's the big deal. They want to be able to control it like alcohol and firearms and make money off of the taxes too, just like the states that have legalized it. It's always about the money and control.
