What Are Mushroom Gummies Side Effects?

Mushroom gummies (both the kinds used for health & wellness and the kinds used for trips) have absolutely exploded in popularity on the internet. 

There are so many uses for these gummies, including stress relief, focus enhancement, immune boosting and even spiritual journeys.

That being said, these mushroom candies can have side effects depending on the type of mushroom used.

To better understand these effects, we'll first distinguish between functional mushrooms and psychedelic mushrooms. Then we'll dive into the specific side effects for each shroom type under both categories. 

Functional vs. Psychedelic Mushrooms: A Simple Breakdown

Functional Mushrooms:

These include mushrooms like lion’s mane, reishi, chaga, cordyceps, maitake, shiitake, turkey tail, and more. They are non-psychoactive and are primarily used for their purported health-supporting properties, such as improving immunity, boosting cognition, and increasing energy levels.

Psychedelic Mushrooms:

Psychedelic mushrooms include species like psilocybin-containing mushrooms and Amanita muscaria, which have psychoactive compounds that can alter perception, mood, cognition and even reality. These mushrooms are typically used recreationally, spiritually or for therapeutic purposes but come with a much higher risk of side effects.

Side Effects of Psychedelic Mushroom Gummies

Psychedelic mushrooms have psychoactive properties that can result in both mental and physical side effects, particularly when taken in higher doses.

These types of gummies will indeed get you "high" or will encourage subperceptual effects when consumed in a microdosed fashion. 

The specific side effects depend on the type of mushroom consumed.

Types of Psychedelic Mushrooms

• Psilocybin Mushrooms: These include varieties such as Psilocybe cubensis, Psilocybe semilanceata (Liberty Caps), Psilocybe azurescens, and Psilocybe cyanescens.

• Amanita Mushrooms: Amanita muscaria (Fly Agaric) is another type of psychoactive mushroom, though its effects are due to ibotenic acid and muscimol rather than psilocybin.

Psilocybin mushrooms make you feel "high", connected with yourself and nature, and highly emotional. They encourage vivid colors, patterns, or other mild hallucinations. They’re great for introspection or feeling “one with the universe.”

Amanita muscaria feels more sedative and surreal. Instead of hallucinations, you might feel drowsy, euphoric, or like you’re in a strange, vivid dream. At higher doses, it can make you confused or clumsy.

The main difference is that psilocybin is more about heightened awareness, while Amanita feels more like a dream state.

Mental Side Effects (Psilocybin Mushrooms)

• Anxiety or panic attacks
• Hallucinations and distorted perceptions
• Confusion or disorientation
• Emotional instability or mood swings
• Temporary paranoia or fear

Physical Side Effects (Psilocybin Mushrooms)

• Nausea and vomiting
• Increased heart rate
• Muscle weakness or tremors
• Dilated pupils and light sensitivity
• Fatigue or lethargy after the experience

Side Effects of Amanita Mushrooms

• Nausea, vomiting, and abdominal discomfort
• Confusion, delirium, or dream-like states
• Muscle twitching or spasms
• Drowsiness or lethargy
• Risk of poisoning if improperly prepared

Factors That Influence the Side Effects of Mushroom Gummies

The side effects of mushroom gummies can vary significantly based on several factors:

1. Dosage: Larger doses increase the likelihood and severity of side effects, especially for psychedelic mushrooms.
2. Type of Mushroom: Different mushrooms have unique compounds, which result in varying side effects.
3. Individual Tolerance: Those who regularly consume mushrooms may experience fewer side effects due to tolerance, while beginners may feel stronger effects.
4. Body Weight and Metabolism: Smaller or lighter individuals may experience more pronounced effects.
5. Preexisting Conditions: Medical conditions, such as mental health disorders or blood sugar issues, can amplify certain side effects.
6. Combination with Other Substances: Mixing mushrooms with alcohol, caffeine, or medications can exacerbate side effects.
7. Set and Setting (for psychedelics): The environment and mental state during consumption significantly impact the experience.
