Heres just a few...
1. (Q) How long should you really hold your hits in?
If youre an experienced marijuana smoker then you are probably set at being able to hold your hits in practically as long as you want. If youre new to marijuana smoking chances are your hit-holding ability will not be that great, it is a skill that comes with time.
Several medical studies by high-end organizations have stated that beyond 10 seconds of holding in your marijuana smoke youre simply wasting your breath. This, for the most part is true. After 10 seconds your lungs have absorbed all the THC out of the marijuana smoke that is possible for your lungs, but that doesnt mean all of the THC is gone from the remaining smoke, sure alot of it is but there it still at most 25% THC left in that smoke so you can recycle it whichever way you want, whether that means blowing it in your cats face or get your girlfriend to suck it up for her own lightweight hit.
But why do I get higher after holding my hit in for 1 minute plus?
Simple answer. Your brain is being deprived of the oxygen that youd normally get during that entire time. Sure, you get a head rush but thats due to a lack of oxygen being combined with the effects of marijuana. Other than that, holding your hit in for that long does not get you higher by absorbing more THC.
Some people simply prefer to hold their hits in until they pass out, others who dont want to kill that many braincells due to lack of oxygen will find that after 10 seconds theyre done.(weedsmokersguide.com)
2. A study done by a group of doctors in Canada at Dalhousie University, concluded that more than 90% of the THC is absorbed into the lungs within the first seconds of inhalation. Another study confirms this, but they put their number at 95% absorption. The 5-15% of THC that isn't absorbed is due to THC loss in trace smoke, or smoke that never enters the lungs.

3. NORML sponsored study showed holding it in for more than 5 seconds was pointless and could be harmful from the lack of oxygen and giving your lungs more time to absorb the bad shit. (420.com)
MEDICAL MARIJUANASmoking is the most expedient method of using medicinal marijuana. The effects are more controllable and are experienced within moments. The downside is that the smoke produced when smoking marijuana contains a number of irritants andcarcinogens. However, According to a 2006 study,* found that there is absolutely no link between smoking marijuana and cancer--even in heavy, long-term marijuana users. Additionally, a 2007 American Association for Cancer Research study** found that marijuana cuts lung cancer tumor growth in half.
4. If you choose to smoke medical cannabis, try the following strategies to reduce some of its risks:
Medicate with more potent cannabis. Smoking cannabis with a higher TCH content reduces exposure to irritating tars, since less cannabis is required to reach the effective dosage.
Use a vaporizer or pipe. The most recommended method of smoking marijuana is through a vaporizer, which significantly reduces exposure to carcinogenic smoke. If you use a pipe with cannabis, it enables more consistent and predictable dosage than a joint. If you prefer smoking joints, use a filter and opt for a rolling paper made from plant cellulose.
Don't hold your breath. Holding your breath after inhaling cannabis smoke does NOT absorb more THC. Doing so will only coat your lungs with more tar. When smoking medical cannabis, inhale deeply, then immediately exhale. (
