Notes

Based on my review of the search results, I did not find any studies or journals that directly equate the adverse effects of pornography as being more harmful than drug use. The research generally compares pornography addiction to drug addiction in terms of similar neurobiological mechanisms and effects on the brain, but does not claim pornography is more harmful. Here are the key points I found:

1. Several studies draw parallels between pornography addiction and drug addiction in terms of brain effects and addiction processes[1][4][6]. For example:

- Both activate similar reward pathways in the brain involving dopamine[4][6].
- Both can lead to tolerance, escalation of use, and withdrawal symptoms[4][6].
- Both can cause hypofrontality (reduced prefrontal cortex activity)[5].

2. One expert compared pornography addiction to crack cocaine addiction in terms of its addictive potential, especially for young people[7]. However, this was presented as an analogy rather than a claim that pornography is more harmful.

3. Studies note that pornography addiction and substance addiction often co-occur and can reinforce each other[6].

4. Research indicates pornography addiction can have serious negative effects on relationships, mental health, and daily functioning[6][7]. However, the studies do not claim these effects are necessarily worse than drug addiction.

5. Treatment approaches for pornography addiction are similar to those used for substance addictions, including psychotherapy and in some cases medication[6].

In summary, while the research draws many parallels between pornography and drug addiction, I did not find evidence of studies concluding pornography addiction is definitively more harmful than drug addiction. The research seems to focus more on similarities in addiction processes rather than comparing levels of harm.
