The combination of bupropion (Wellbutrin) and lysergic acid diethylamide (LSD) is medically inadvisable due to a serious and potentially life-threatening risk of adverse drug interactions. Bupropion is a prescription medication used to treat major depressive disorder and as an aid for smoking cessation, while LSD is a powerful hallucinogen with no approved medical use. Introducing LSD into a regimen that includes a prescription drug creates an unpredictable and dangerous chemical environment. The primary concerns center on the physical danger of seizures and complex complications within the brain’s neurotransmitter systems.
How Bupropion and LSD Affect the Brain
Bupropion and LSD exert their effects on the central nervous system through distinct pharmacological pathways, setting the stage for complex interactions. Bupropion is classified as a norepinephrine and dopamine reuptake inhibitor (NDRI), meaning it increases the concentration of these two neurotransmitters in the synaptic cleft by blocking their reabsorption into the pre-synaptic neuron. Unlike many common antidepressants, bupropion is generally considered to be devoid of clinically significant activity on the serotonin system. (59 words)
LSD, conversely, is a classic psychedelic whose effects are fundamentally rooted in the serotonin system. LSD acts as a powerful partial agonist primarily at the serotonin 5-HT2A receptor subtype, which is highly expressed in areas of the brain responsible for mood and perception. The activation of this receptor is directly responsible for the substance’s profound hallucinogenic and altered consciousness effects. While LSD’s primary target is the 5-HT2A receptor, it also has affinity for other serotonin, dopamine, and adrenergic receptors. (89 words)
The Primary Physical Risk of Combining Them
The most immediate and severe physical danger of combining bupropion and LSD is the significantly increased risk of seizure activity. Bupropion is known to lower the seizure threshold in a dose-dependent manner, meaning it makes the brain more susceptible to uncontrolled electrical activity, resulting in convulsions. For the immediate-release formulation of bupropion, the seizure incidence at the recommended daily dose of 300 to 450 milligrams is approximately 0.4%, but this risk climbs sharply at higher doses.

The addition of LSD, which affects multiple neurotransmitter systems including dopamine and adrenaline, can further destabilize the central nervous system. While LSD is not a classic CNS stimulant, its effects can induce a state of CNS excitability, characterized by increased heart rate and elevated blood pressure. This generalized neural excitability, combined with bupropion’s seizure-lowering property, creates a hazardous synergy that heightens the probability of a seizure. (88 words)
The combination introduces a physical danger that is a genuine medical emergency. The risk is compounded by bupropion’s inhibition of the CYP2D6 enzyme, which can affect the metabolism of other drugs in the body. Nonetheless, any substance that adds to the overall excitability of the brain can tip the balance over bupropion’s already compromised seizure threshold. (65 words)
Serotonin System Complications
Beyond the direct physical danger, the interaction between bupropion and LSD can lead to two distinct complications involving the serotonin system: the blunting of LSD’s effects and a theoretical, though less direct, risk of Serotonin Syndrome. LSD’s profound effects are entirely dependent on its ability to activate the 5-HT2A receptors, and any interference can alter the experience in unpredictable ways. Bupropion’s action on dopamine and norepinephrine can indirectly influence the downstream signaling pathways that LSD activates. (93 words)
The interaction may lead to a phenomenon called blunting, where the psychedelic effects of the LSD are significantly reduced or completely absent. Users may find the experience is dampened or less intense. This blunting effect can prompt an individual to take a higher, riskier dose of LSD in an attempt to achieve the desired effects, inadvertently magnifying the seizure risk already posed by the bupropion.

While bupropion is not a primary serotonergic agent, cases of Serotonin Syndrome have been reported when it is combined with other serotonergic drugs, particularly in overdose situations. Serotonin Syndrome is a potentially life-threatening condition caused by excessive serotonin activity, leading to symptoms like agitation, confusion, muscle rigidity, and hyperthermia. LSD’s potent activation of the 5-HT2A receptor could theoretically contribute to or complicate a presentation of Serotonin Syndrome. (102 words)
Introducing a powerful psychedelic like LSD also carries a substantial psychological risk for individuals who are already being treated for mental health conditions with bupropion. Psychedelics are known to destabilize mood and can precipitate acute episodes of anxiety, panic attacks, or even psychosis, especially in vulnerable individuals. The underlying mental health issues for which bupropion was prescribed are already a risk factor, and the potent psychoactive effects of LSD can overwhelm the brain’s ability to maintain emotional and psychological stability.

Essential Safety and Medical Warnings
The use of bupropion and LSD together is unsafe and must be avoided due to the documented medical risks. Bupropion is a medication prescribed by a physician under careful medical supervision, and its use should never be combined with illicit substances without consultation. The most prudent course of action is to speak honestly with a healthcare provider before making any changes to a prescription regimen. (68 words)
Medical professionals cannot endorse or advise on the use of illegal drugs, and LSD is classified as a Schedule I controlled substance. Self-medicating or experimenting with this combination bypasses the protective measures of medical oversight and places the individual at significant risk. Any decision to alter a medication schedule, including stopping bupropion, must be made in consultation with a physician who can guide a safe and gradual dose taper. (78 words)
For individuals who may disregard these warnings, harm reduction principles dictate minimizing the dose of both substances and having a sober, trusted person present for the entire duration. Given the severe and unpredictable nature of the seizure risk, complete abstinence from the combination is the safest approach. Immediate medical attention must be sought if symptoms such as muscle twitching, confusion, rapid heart rate, or fever develop, as these may indicate a severe adverse reaction like a seizure or Serotonin Syndrome.
