The bottom line No known interaction

We found no known interaction between Tree Tobacco and Amphetamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Interaction report

Tree Tobacco and Amphetamine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Amphetamine and Tree Tobacco in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Tree Tobacco at all — not against Amphetamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Tree Tobacco Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for Tree Tobacco on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Tree Tobacco, this list is the first place to look. 5 entries are worth acting on rather than waiting out — marked below.

  • Muscle weakness / Hallucinations Worth acting on Additional detail

    “Orally, tree tobacco is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Tree tobacco can cause nausea, vomiting, diarrhea, abdominal pain, changes in blood pressure and heart rate, muscle weakness and paralysis, respiratory distress, and neurological symptoms including vertigo, confusion, fatigue, headache, hallucinations, spasms, weakness, and coma.”

About Tree Tobacco

What is Tree Tobacco?

  • Topical use on wounds or sores (folk use)
  • Joint and muscle pain (folk use)
  • Headache relief (traditional poultice)
  • Insect or pest control

Tree tobacco is a poisonous shrub that contains the toxic alkaloid anabasine, and it is not a safe dietary supplement. There is no reliable evidence that it treats any condition, and swallowing it can cause severe poisoning or death. We strongly recommend avoiding internal use entirely.

Nicotiana glauca · Solanaceae · Leaves · Crushed leaves, poultices, traditional topical preparations

An interaction check asks whether these two react with each other — it does not ask whether Tree Tobacco is a good idea for someone in your situation. Here is what our Tree Tobacco record says about it on its own.

Tree Tobacco: dosing

There is no safe or established dose for tree tobacco. It is not sold or recommended as a standardized dietary supplement, and no amount is known to be safe to swallow.Because of its toxicity, we recommend avoiding it entirely.

Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group.

Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.
