    DENVER, CO — Lawmakers took a step toward implementing Colorado’s recreational marijuana law on Tuesday when they set blood-level limits for driving, but a measure to tax retail pot was in limbo a day before the legislative session was set to end.

    Along with Washington state, Colorado voters in November approved the use of small amounts of marijuana by adults. The Colorado vote directed state lawmakers to set up a regulatory framework for the sale and taxation of cannabis.

    The driving-while-stoned bill sets a 5-nanogram-per-milliliter threshold for tetrahydrocannabinol, the active ingredient in marijuana. The proposal now heads to Governor John Hickenlooper, who has indicated his support for the measure.

    “I think this is an important part” of regulating pot, Hickenlooper, a Democrat, told reporters on Monday.

    Washington had the 5-nanogram limit set in its ballot language that voters approved in November.

    Colorado legislature had failed in its previous attempts to impose a marijuana limit for driving under the state’s medical pot law, which has been in effect since 2001.

    Still pending in the legislature is a measure to tax recreational pot, which under the state constitution requires voter approval to implement. It is unclear what the ramifications would be for pot legalization if it fails.

    The state Senate gave initial approval on Tuesday to impose a 15 percent excise tax and a 10 percent sales tax on retail pot sales. A final Senate vote is to be taken on Wednesday before it heads back to the House, where a final vote will need to be recorded before the session expires at midnight in order for it to move to the governor’s office.

    The state House of Representatives passed a bipartisan resolution asking for direction from the federal government, which considers marijuana an illegal narcotic, on how to proceed with regulating recreational pot.

    “We need to know how the federal government is going to approach this issue,” House Republican leader Mark Waller said in a statement.

    “In less than a year, Coloradans will begin buying and selling marijuana, and we need to be sure we implement (the law) in a way that respects the will of voters and clarifies our understanding of both federal and state law.”

    My name is Jason Jones. I'm from Rochester, MN and I'm 35 years old. I scrap metal and work as grounds keeper at a local trailer park. In the winter, I shovel a bunch of driveways and sidewalks to make some extra money and to stay busy. In my free time, I try to find interesting articles about the war on drugs that I can post on Drugs-Forum, so that the information can reach a wider audience.

    What amount of cannabis does 5 nano-grams per milliliter equal?
  2. SmokeTwibz
    I was hoping that maybe somebody here would know what that meant..... because I have no idea. It doesn't sound like very much.

    There is no universal public standard to this legislature. The THC content of marijuana varies greatly from one plant to another. It would be very hard for your average pot smoker to measure this prior to ingestion in order to keep their levels below 5ng/ml.

    The problem with this legislature is that even with drug tests at a cut off of 20ng/ml THC can still be detected 2-6 days after it is smoked depending on the THC content of the marijuana. Even GC/MS testing with a cutoff of 15ng/ml can result in positive tests for up to 5 days. Federal guidelines for drug testing place the cut off for THC at 50ng/ml. The lower you set the cutoff, the higher percentage of positive drug tests will come back, even from the most casual recreational users days after they have smoked.

    5ng/ml is extremely low and could classify pot smokers as unable to drive at all without risking a citation.

    Is the 5ng/ml blood or urine? Wouldn't there be a difference?

    The setting of the limit is kind of irrelevant. Its the sensitivity of the saliva panel test that counts because you have to fail a roadside test before any B sample is sent off for lab testing. I can tell you from experience that you have to be stoned out of your mind to return a positive test on the saliva panels they use in Australia.

    I expect that Colorado will use the same Securetec Drugwipe type testers we do going by the uptake of the product by police wanting a proven system that is well documented and ready to go. Even if it ends up being a Standard Impairment Assessment (SIA) and you fail, your to stoned to drive and you deserve whats coming to you. What the state sets the limit at is only relevant to circumstance and enforcement.

    Standard Impairment Assessment (SIA)

    There are four parts to the assessment:
    1. Interview and observation
    2. Physical impairment test
    3. Walk and turn test
    4. One leg stand test
  6. stryder09
    Yes, very large difference.

    This would be blood testing. Not urine testing.

    Typical cutoff for active THC in blood testing is 0.5-1 ng/mL. Cutoffs for THC metabolite in urine typically are 5, 15, 20 or 50 ng/mL depending on the application.

    would not blood testing take forever? i mean they are dealing with motorists! bts this goverment website says that you get 5 ng/mL in your blood after 3 hours pass after smoking... so you will be like 1.5hours not high at by the time of check-up that may still show you above the limit. "Plasma THC concentrations generally fall below 5 ng/mL 3 hours after smoking for 17% thc strain" still it depends on your strain, what if its 26%?

    This is a bit off topic but made me wonder. We have "open container" laws for alcohol, but can a passenger smoke so long as the driver is sober?
  9. Großschmackhaft
    Correct me if i'm wrong, but if those values can be found days after the consumption of cannabis, then they are not referring to the THC, but THC metabolites, right? While the new legislation is for unmetabolized THC.
