What This Study Found

Both patients, who had used cannabis for 9 and 14 years respectively, had abnormal blood levels of homocysteine, vitamins, and cortisol. After two months of targeted supplementation and psychotherapy, both improved and reduced their cannabis consumption.

Key Numbers

Patient 1: 28-year-old man, 9 years of use (3x/week). Patient 2: 39-year-old man, 14 years of use (2x/week). Both improved after 2 months of treatment.

How They Did This

Case report describing the clinical management of two long-term cannabis users treated with nutritional supplements (folic acid, methylcobalamin, pyridoxine, vitamin D, Rhodiola rosea, L-tyrosine) and psychotherapy.

Why This Research Matters

Long-term cannabis use may be associated with nutritional and hormonal imbalances that could contribute to symptoms like fatigue, anxiety, and depression.

The Bigger Picture

These cases suggest that addressing nutritional deficiencies in long-term cannabis users may improve symptoms and potentially reduce consumption, though the evidence is extremely limited.

What This Study Doesn't Tell Us

Only two patients with no control group. Multiple interventions were given simultaneously, making it impossible to isolate which treatment drove improvement.

Questions This Raises

  • ?Are vitamin deficiencies and hormonal changes more common in long-term cannabis users?
  • ?Would supplementation alone reduce cannabis use without psychotherapy?

Frequently Asked Questions

What nutritional problems were found?

Both patients had elevated homocysteine, low vitamin levels, and low cortisol. They were treated with B vitamins, vitamin D, Rhodiola rosea, and L-tyrosine.

Can this prove cannabis caused the deficiencies?

No. With only two patients and no control group, the study cannot establish causation between cannabis use and the nutritional findings.
