Why this applies to Amphetamine Aspartate, Amphetamine Sulfate, Dextroamphetamine Saccharate, Dextroamphetamine Sulfate

Amphetamine Aspartate, Amphetamine Sulfate, Dextroamphetamine Saccharate, Dextroamphetamine Sulfate falls under STIMULANT DRUGS — the group 1,3-dmba interacts with.

Theoretically, combining 1,3-DMBA with other stimulant drugs might increase the risk of cardiovascular toxicity.
Animal research shows that 1,3-DMBA has stimulant effects, such as increasing blood pressure and heart rate.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing about pairing 1,3-DMBA with your Adderall: both are stimulants, and stacking two stimulants together can add up in ways that are hard on your heart. Adderall already revs up the same fight-or-flight system, raising heart rate and blood pressure. Throw in a second stimulant like 1,3-DMBA and you may push those effects higher than intended.

What could that feel like? A racing or pounding heartbeat, jitteriness, chest discomfort, spikes in blood pressure, anxiety, or trouble sleeping. The bigger worry is the strain on your heart and blood vessels. To be honest, the evidence here is mostly from animal studies, so it's more of a reasonable caution than a proven danger. Still, 1,3-DMBA isn't a safe or approved ingredient to begin with. Please talk with your pharmacist or doctor before combining anything like this.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

2 of 2

Amphetamine Aspartate, Amphetamine Sulfate, Dextroamphetamine Saccharate, Dextroamphetamine Sulfate also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.

Theoretically, 1,3-DMBA might modestly increase the levels of CYP2D6 substrates.
In vitro research shows that 1,3-DMBA weakly inhibits CYP2D6 enzymes.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing 1,3-DMBA with your Adderall (amphetamine/dextroamphetamine). On paper, 1,3-DMBA is a weak blocker of an enzyme called CYP2D6, which is one of the pathways your body uses to clear amphetamines. If that pathway slows down a little, your Adderall could hang around slightly longer and feel a touch stronger. In theory that might mean more of the usual amphetamine effects: faster heartbeat, higher blood pressure, jitteriness, trouble sleeping, or reduced appetite.

That said, this is only an in vitro (test tube) finding, and the effect looks minor. My bigger worry is that 1,3-DMBA is itself a risky, FDA-flagged stimulant. Stacking two stimulants strains your heart. I'd really encourage you to talk with your doctor or pharmacist before combining them.
