Bodyweight quick formula

For a 70 kg adult, divide the total mg dose by 70 to get your mg/kg ratio. Most published ranges assume this reference weight. If you weigh significantly less, reduce proportionally; significantly more does not always mean linearly higher doses.

FAQ.

What is a safe Opiaten dose?
A "safe" dose depends on body weight, tolerance, set and setting. Start at the threshold or light range for your chosen route and do not redose until onset is complete.
How do I calculate Opiaten dose by weight?
For substances where bodyweight matters: divide the mg amount by your weight in kg to get the mg/kg ratio. Most common dose data assumes a 70–80 kg adult.
What happens if I take too much Opiaten?
Exceeding the "heavy" range significantly increases risk of adverse effects, medical emergency, or overdose. Harm reduction starts with knowing the ranges.
How long does Opiaten last?
Duration varies by route. The timeline section below shows onset, peak, offset and after-effects for each route.
Can I mix Opiaten with other substances?
Many combinations are dangerous. Check the interaction checker tool before combining anything. Never combine on a first experience.
Is Opiaten dosage the same for all routes?
No. Bioavailability differs significantly by route — intranasal and IV routes typically require lower doses than oral for equivalent effect.
Should I weigh my Opiaten dose?
Always. A milligram scale (0.001g precision) is essential for most substances. Volumetric dosing with a solvent is the gold standard for sub-10mg doses.
