When it is time to boil off the alcohol, you have one of two options. The first is to use a double boiler and a range. This is a very safe method. Fill the bottom part of your double boiler with water. Pour the dark green liquid into the top pan. If you can not fit all of the liquid in the pan, gradually add it as the level drops. Turn the burner on high and wait for the liquid in the top pot to boil. Once the liquid in the top pot is bubbling (the alcohol is evaporating), turn off the burner immediately. The heat from the boiling water below will continue to burn off the alcohol. Allow the contents in the top pan to bubble for 15 to 25 minutes. Occasionally scrape the sides and bottom of the pan with your silicon spatula. If the contents stop bubbling, but still appear runny, turn on the burner to low. Once the contents resume bubbling, turn off the burner. When the contents become a thick dark green syrup, all of the alcohol has evaporated and all you are left with is the medical cannabis oil. The process is complete. Remove the top pan from the bottom pan and allow the medical marijuana oil to cool. As it cools, it will continue to thicken. If you do not have access to a stove top, you may substitute a rice cooker for a double boiler. Fill your rice cooker of the way full with your alcohol-oil mix. If you have more of the mixture, you can continue to add it to the rice cooker as the level drops. Turn the rice cooker on "High" or set it to the "White Rice" setting. Allow the solvent-oil mixture to boil down. When the solvent-oil mix is becomes a thick, dark green liquid, put on oven mitts, remove the pan from the rice cooker, and gently swirl the mixture. (When the amount of bubbles rising to the top decreases significantly, it is time to remove the mixture from the rice cooker). Pour the contents of the rice cooker into a glass or metal dish. Set the glass or metal dish on a candle warmer. Turn on the candle warmer and allow any remaining CO2 to evaporate from the mixture. When the contents are no longer bubbling, you may remove the glass or metal dish from the candle warmer. The lack of bubbles signifies that all of the alcohol has evaporated from the medical cannabis oil and the process is complete. For ease of use, store the medical marijuana oil in a plastic syringe. Slowly draw the medical cannabis oil into the plastic syringe by pulling on the plunger. If you have more oil than syringes, you may store any excess oil in a glass air-tight container. Keep your syringes and containers in a cool, dark cabinet.

Summary: Boil off the solvent in a double boiler. Boil off the solvent in a rice cooker. Fill syringes with the medical marijuana oil.

Certain medical conditions could prevent you from boxing. Make sure to consult a physician before you start training. If you are prone to seizures or have a neurological problem, you should not spar. Talk to your doctor to see what they recommend. For some conditions you'll be able to train, but will be advised against fighting. If you have heart disease, asthma, diabetes, cancer, or lung disease, consult a doctor before starting a new workout routine. Learning how to fight without the proper training can be a detriment. You could be utilizing poor technique during practice and reinforcing bad habits which may be hard to unlearn down the road. You also could be practicing in an unsafe environment and could hurt yourself or your training partner. When starting off, go to a certified gym with trainers who have experience. Your hands are the most valuable tool for boxing and must be preserved for you to compete. Many amateurs will put on boxing gloves without wrapping their hands first. This could cause serious injuries in your hand, knuckles, or wrists that could end your boxing career. Wrapping your hands will prevent injury and reduce swelling and pain after punching. Always take precautions or someone could get seriously injured. Wear a mouthguard, headgear, and a cup so that you protect yourself during practice. Sparring without a mouthguard could result in a cut lip, cut tongue, or a broken tooth. Even light punches could cause serious injury if protective gear is not worn. Your experience as a boxer also comes with a new responsibility to keep a calm and cool head when outside of the gym. Taking your skills to the street and provoking fights could get yourself or someone else seriously injured or could even be fatal. Because you're the one with the training, you could face serious penalties or jail time. Avoid fights at all costs and try to resolve your problems with words. In dire circumstances use your skills for self-defense. To avoid a fight you could say something like, "I'm a trained fighter and I do not want to fight you. Please leave me alone." Your instructor will know how to train you safely and properly. Even if you have experience competing, always remain respectful towards your instructor. They may see something that you can improve on. Ultimately they are the expert, and you are the student so you must follow their directions to improve.
Summary: Go to a doctor before you start boxing. Don't fight without proper training. Keep your hands wrapped when punching. Always wear protective gear when sparring. Never start fights. Respect and listen to your instructor.
