My doctor didn't explain me how to use marijuana properly. He only said that there are many ways to use marijuana and advised me to look for information on the Internet. I found on the Internet an excellent article
http://www.ncsm.nl/english/diy/smoke-use-hash-oil how to smoke hash oil. I found the most convenient solution for me. You can smoke marijuana through a wipe or bong, you can cook with marijuana, you can smoke marijuana through the tube.
