1) Yes. Make sure you have the proper paperwork, though.

2) Yes, you may purchase from any dispensary.

3) Some places off free eighths every month or discounts off or a membership price. First, find a place that cares about your health and who sells top shelf at reasonable prices. My caregiver sells bud that I love for $280/oz. I wouldn't expect freebies, but they exist, especially if you have a very serious condition.

4) You can find vaporizers at head shops and some dispensaries. Sometimes the markup is outrageous, but some places sell them at cost. There are so many different types of vaporizers to choose from. I've read many different reviews and the only conclusion that I could draw is that the Volcano types are the best way to go, but are the most expensive. Prices are finally coming down, but expect to pay at least a couple hundred dollars for a generic one. I'm sure you could find one on ebay or craiglist for a reasonable price. You can try one out for yourself if you'd like at the Healing House.
