How come you don't have to be 18 to buy caffeinated products?

The x axis is a ratio and the y axis is a ranked judgement by psychiatrists. Neither have units of measure.

It's a ratio of doses, the result is correctly without units.

>> No.3593982

the active/lethal dose axis is obviously a percent of the lethal dose, with 1 being lethal. In caffines case you need 100 times more than has an effect on you to kill you.

i should be dead apparently

BUT DOSE ITSELF SHOULD HAVE A UNIT OF MEASUREMENT OR ELSE THE RATIO IS MEANINGLESS.

LSD's lethal dose ratio may be absurd (it's probably even less than 0.001), but I can guarantee that if you take 100x the active dose, it will alter your mind and "you" won't be back for several years, if ever.

Also, it's a lot easier to physically ingest 25x too much mescaline than it is to drink 10x too much alcohol.

And I'm saying this as a drug guy. Know your fucking dose.

I would still encourage everyone to take LSD and shrooms at least once.

No, it means the dose at which you begin to feel the desired effects of the drug. Do you get a "buzz" from 1 beer?

I get a "buzz" from 4 oz of liquor. If I drank a 40, I would probably die. Especially if it was all at once.

>The LD50 of caffeine in humans is dependent on weight and individual sensitivity and estimated to be about 150 to 200 milligrams per kilogram of body mass

>Smit HJ and Rogers PJ. Effects of low doses of caffeine on cognitive performance, mood and thirst in low and higher caffeine consumers. Psychopharmacology 2000;152:167–73.

shows that a dose as low as 12.5mg effects adult males with caffeine tolerance. note that this is 12.5mg total, not per kg.

the way i read it, it lines up exactly with what you said

4oz= 2.66 drinks right in center of the 1.5-4 they state
and 10x that is lethal dose. which lines up exactly with your 40oz.

That graph is useless and does not represent the danger of the dose needed to gain an effect from the drug. A cup of tea is going to do less damage than the dose of horse tranquilizer needed to give you a high.
