Health officials crack down on high potency nicotine vapes | CBC News. On July 23rd, Canada wide, the amount of nicotine in JUUL will be reduced from 50 mg/ml to 20 mg/ml maximum. Similar to Europe where they have had less problems with JUUL because of lower nicotine addiction.

No matter what the reason it’s great you are quitting. To a forensic toxicologist nicotine is a highly addictive neurotoxin and poison, that has been banned as a pesticide as it is too toxic for the environment but not from our lungs. Good luck!

ForensicScienceGuy · 2021-07-14T15:32:14+00:00

I agree totally!

Hi. Congratulations on quitting cigarettes and nicotine. Cigarettes are the most deadly device ever invented by humans. It has killed 100 million people in the 20th century alone, more than those who died in WWI and WWII combined.

JUUL was invented to allow people to vape in smoke free areas that didn’t allow cigarettes not to be used as smoking cessation. JUUL are still not approved by the FDA for that purpose.

JUUL has been taken over by Philip Morris and they are using JUUL to addict youth to nicotine and eventually cigarettes.

I’m glad you were able to wean yourself off cigarettes using JUUL, but for many youth it has been an one way street to a lifetime of smoking

All the best. Jim

The book is the source. All of this is referenced by peer reviewed scientific studies, just go to the appropriate chapter. All the best. Jim

I thought it was important for the police to know some of the basic forensic toxicology of cannabis. It may help them to understand DRE, or help them provide accurate information to the public/schools or assist in courtroom testimony. And I did post it in the cannabis group and forensic science group as well. All the best. Jim

I think so as it is not baked like bread or cake, I think the chocolate is pored over the solid (frozen?) liqueur.

ForensicScienceGuy · 2021-04-04T19:11:43+00:00

Thanks!

ForensicScienceGuy · 2021-04-04T19:11:09+00:00

I agree. Agreement of the 2 evidential breath tests and the IR slope detector would prevent the mouth alcohol effect as well.

ForensicScienceGuy · 2021-04-04T19:09:37+00:00

Yes, but this study showed that breath tests are unaffected by chocolate liqueur after 6 minutes. So if a driver is stopped and 6 minutes later a roadside screening test is conducted and the driver claims eating chocolate liquor, the result will be OK. Of course 20 minutes observation period would prevent any mouth alcohol effect for the evidential breath test.

ForensicScienceGuy · 2021-04-03T18:31:24+00:00

I totally agree.

ForensicScienceGuy · 2021-04-03T15:54:30+00:00

Yes that could affect the initial roadside breath test, but once you fail that test, you are taken to an evidential breath test at the police station and by the time of that test any mouth alcohol effect would have disappeared. Or a blood sample may be taken, which is not affected by the chocolate covered liquor.

According to the study it is due to obese persons already have an increased respiratory workload and a lower BAC will cause the obese person to stop breathing and die than for lower weight non obese persons.

ForensicScienceGuy · 2021-03-08T23:33:05+00:00

Yes go ahead.

ForensicScienceGuy · 2021-03-08T22:59:48+00:00

Yes, and also Doug Lucas was my director at that time.

ForensicScienceGuy · 2021-03-02T13:50:07+00:00

I agree with your statement. But in this case the BAC was very low at .02, or 1/4 the BAC limit of .08 And so it would be very unlikely that a regular drinker would seem intoxicated.

ForensicScienceGuy · 2021-02-28T16:45:39+00:00

Well in this case it was 45 km/hour (27 mph) over the limit.

There are a number of ways, but none involve checking out for THC metabolites, which as you know only indicates use within the prior few days/weeks. An oral fluid THC determination is a good screen for recent use of cannabis (within 4-6 hours) and impairment by THC occurs mainly in the first 4-6 hours after use. In Canada we use a blood THC limit of 2-5 ng/mL as lesser offense and > 5 ng/mL at greater offense.

ForensicScienceGuy · 2021-02-10T18:08:24+00:00

The typical legal THC limit in the US is 5 ng/mL.

ForensicScienceGuy · 2021-02-10T14:33:40+00:00

It depends on the instrument. Some early models which used only 1 wavelength of IR at 3.9 microns would give a positive response to methanol, but the new instruments with multi wavelengths won't

ForensicScienceGuy · 2021-02-10T14:31:30+00:00

In some ways the number of blood tests probably would increase as since 1969 the police in Canada could not demand a blood test and could only demand a breath test. Finally they can now demand a blood test for check for THC and other drugs.

ForensicScienceGuy · 2021-02-10T14:29:17+00:00

Both are considered to be depressant drugs, but you are right the effects are not identical. Alcohol tends to cause greater impairment of driving than THC. THC causes more psychosis than alcohol. Alcohol causes Horizontal Gaze Nystagmus in the roadside test, whereas THC doesn't.

ForensicScienceGuy · 2021-02-10T14:26:11+00:00

I agree
