Mainly due to ignorance. Ignorant people are either particularly radical or particularly conservative.

Everyone needs to understand a fact: discussions on social media often lag behind reality. Because those discussing are behind the actual situation.
1 Just now, a province's anti-drug regulations have been released, having just been approved in full in recent days. It clearly states that for drug users, if they voluntarily go to a qualified institution for drug rehabilitation, public security organs will not punish their drug use behavior.
2 Furthermore, it re-emphasizes: drug rehabilitation personnel will not face discrimination in education, employment, and enjoying social security. This point will not change for many years.
Also, drug users with a long-term low risk of relapse, after assessment, may no longer undergo face-to-face inspections, drug tests, counseling sessions, and early warning. So, this past couple of days, a guy who has been constantly checked for 12 years has reason to complain. He visually meets the criteria for this new policy.
3 Many of your concerns are unnecessary. Please see:
1 All drug users must register, with public security organs conducting dynamic control.
2 Those transferred to community drug rehabilitation must report to the local town government or street office within the deadline. Otherwise, they will bear the consequences.
3 It clearly requires industry prohibitions. First, key positions in urban transportation, such as drivers, signal workers, and dispatchers. Second, school bus drivers. Third, positions in kindergartens, and fourth, other prohibited employment positions.

This is what I repeatedly educate and explain: many people are behind the times because they do not understand reality and are too lazy to learn about it. They always resort to conspiracy theories, talking about learning from the West, traitors, collaborating with the enemy, and pushing doors. This is a problem.
"You" insist on not treating drug users, rehabilitation personnel, and those in recovery as human beings, as fellow citizens for various reasons. However, the law, anti-drug regulations, and judicial administrative work will treat people as people. This is a curious phenomenon that even foreign Chinese observers have noticed: many Chinese are more conservative and radical than their government.
95% of radicalism is inseparable from ignorance. Ignorance of the actual situation. For instance, ignorance regarding the actual drug situation, types of drugs, the anti-drug and rehabilitation work system, registration and dynamic control of rehabilitation personnel, and the situation of long-term low-risk individuals who have already quit. Do you agree with this point?
