Someone on Reddit asked if switching from alcohol to a THC-infused drink while starting two peptides — Reta and GHK-Cu — would be okay. They said they plan to stop drinking alcohol while taking these peptides and wondered if a THC drink (like a commercial product) would interact with the peptides or have similar effects. The post is a casual question, not a scientific study, so it’s basically asking for other people’s experience or any known risks. GHK-Cu is a small protein fragment (a peptide) that naturally occurs in the body and is often used in skin and wound-healing products; people sometimes take it for skin repair or hair reasons. “Reta” is less familiar in mainstream medical literature and might be a brand name, nickname, or a less-studied compound. In plain terms, peptides are short chains of amino acids that can mimic or influence natural signals in the body. They are not the same as drugs like antidepressants or alcohol; their effects depend entirely on what peptide you’re talking about. There’s no solid published evidence saying THC drinks and these specific peptides interact. Most safety data about peptides like GHK-Cu come from topical (skin) use or limited research, not large human trials. THC (the part of cannabis that causes the “high”) acts on brain receptors involved in mood and appetite, while many peptides work locally or through different biological pathways. That means an interaction is possible but not guaranteed; it largely depends on how the peptide is taken (injected, applied to skin, or oral), how much THC you’d consume, and your own health and medications. The Reddit post is just one person asking; it doesn’t report a study or proven outcomes. For a regular person thinking about this, the practical takeaways are simple: stopping alcohol while trying a new health product can reduce known harms from alcohol. Trying a THC beverage instead isn’t an obviously safer or equivalent swap — THC affects your brain and can cause impairment, anxiety, or other side effects, and commercial THC drinks vary in strength. If the peptides are prescribed or come with medical guidance, tell your clinician about any cannabis or other substance use. If the peptides are self-administered products bought online, be extra cautious because dosing, purity, and the way they’re made can be uncertain. Some important cautions: THC can interact with prescription drugs (through how the liver processes chemicals) and can affect mood, coordination, and thinking. The safety of many non-prescription peptides for oral or injected use is not well-established, and side effects can be unknown. Pregnant or breastfeeding people, those with heart or mental-health issues, or anyone on medications should be particularly careful. Also, legal status matters — THC drinks may not be legal everywhere. Because the Reddit post didn’t present any clinical data, there’s no firm answer; consult a healthcare professional before combining cannabinoids with new peptides. Bottom line: there’s no clear evidence from that post that THC drinks will mimic or safely replace alcohol while on Reta or GHK-Cu, so be cautious and check with a clinician.
