Reportedly, the lawyer wanted to fight for Jaycee's basic legal rights but he chose to give them up because he did not want his family to be misunderstood, reports The Straits Times Communities.
Both Jaycee, 31, and his friend, actor Kai Ko, 23, tested positive for marijuana after they were picked up by the police at a foot spa. The police also found more than 100g of marijuana in Jaycee's home.
The writer of the Facebook post, which was republished on Chinese websites such as NetEase, said it was painful to see the stories about Jaycee betraying his friends when he had been "made a scapegoat".
Rumours have been rife that the police have their eyes on more celebrities, including Jaycee's friends.
Yesterday, the Beijing police denied a report that they had made a list of 120 stars from China, Hong and Taiwan, said NetEase.
On Thursday, actor Chen Bo-lin, a friend of Jaycee's, fended off rumours about his connection to the case.
Chen's agent said the actor was "willing to cooperate in the relevant unit's investigation" to prove his innocence. A fan meeting of Chen's that had been scheduled for today in Hefei, eastern China, was cancelled, said Ming Pao.
Chen's agent explained that the event had to be cancelled as it was in danger of being upstaged by unrelated news and that the star was in no mood to smile.
Actor Jaycee Chan is reported to have finally met his lawyer in prison in Beijing on Thursday, one week after his drug arrest.
