Shen Boyang's drug issue was questioned by the blue camp. Netizens dug up Jiang Wanan's 2021 proposal to counterattack.

A 2014 article by Shen Boyang, a candidate for mayor of Taipei City from the Democratic Progressive Party, about drugs was recently uncovered by Blue Camp, questioning his stance. Shen Boyang expressed today (3) that he is willing to debate this issue with Taipei Mayor Chiang Wanan, and called on Chiang not to create panic and bully Taipei people. Some netizens dug up Jiang Wanan's 2021 legislator's proposal for "methadol replacement therapy for the treatment of heroin addiction" and questioned whether he knew drug addiction was a medical and treatment issue, but now he has changed his mind. After Jiang Wanan posted a post on Facebook in the evening, netizens poured in angrily and questioned her. The post exceeded 100,000 in two hours and could not be deleted.

Jiang Wanan's proposal that year pointed out that the 2010 budget for the "Strengthened Drug Addiction Treatment Services" under the "Psychological and Oral Health Business" of the Ministry of Health and Welfare allocated 81.937 million yuan, which would be used to handle drug hazard prevention and control center consultation hotlines, addiction prevention and treatment seminars, addiction prevention and treatment talent training and other matters. However, since methadone substitution therapy was launched in Taiwan in 1995 for the treatment of heroin addiction, only a few professionals have invested in the clinical treatment and treatment of drug addiction. Currently, professional addiction treatment staff (including addiction specialists and drug addiction case managers) , social workers and psychologists). There are currently only about 200 addiction specialist treatment physicians nationwide. In addition, only 17 hospitals across the country participated in the non-opioid drug addiction treatment subsidy program of the Ministry of Health and Welfare in 206 and 207. Related treatment resources are obviously insufficient. Drug addiction has clinical characteristics of being chronic and prone to relapse. As various emerging drugs invade Taiwan's society and schools, how to improve the accessibility of drug addiction medical treatment and establish a friendly treatment environment is a top priority. The budget for this project has been frozen at 1 million yuan. The Ministry of Health and Welfare will not spend it until the Ministry of Health and Welfare submits a project report to the Social Welfare and Health Environment Committee of the Legislative Yuan on how to promote the investment of medical resources into drug addiction treatment and improve the accessibility and friendliness of relevant treatment resources and obtain approval.

Jiang Wanan also posted on Facebook in the evening, emphasizing that "there is no room for ambiguity in the fight against drugs. Prohibiting drugs from entering the campus community is a red line that must be adhered to." Many netizens flooded the bottom with angry comments, and many people even directly posted Jiang Wanan 2021 2019 proposal, Jiang Wanan repeatedly questioned Jiang Wanan’s position and asked Jiang Wanan to debate with Shen Boyang; however, many netizens expressed anger that their messages had been deleted, and they continued to express anger. Two hours after the article was published, there were more than 100,000 Facebook comments.
