鸦片烟为中国四千年来未有之毒，今竟于数万里外传染及之，抑且日变月异，几不知迁

物踵此而进，为华人害，世祖不听，棉遂盛传，而其所谓为害者，由今思之，疑即鸦片。故
或于花时择棉之雄者，取根捣汁饮之，即可止瘾，似乎物理相制，其间原有交关云云。据此
则鸦片之害，或不尽由人事，倘得天去其疾，陡绝来源，则是瘾也，岂待戒而始除哉。
泰国的西医有一种名为“听肺木”的工具，长度不超过一尺。遇到患肺部疾病的患者时，将一端放在患者胸前，医生枕住另一端进行听诊。
边听边移动位置，仔细审视患者的呼吸情况，辨别病变的具体部位，从而能够知道疾病所在并进行治疗。
鸦片烟是中国四千年来从未有过的剧毒之物，如今竟然从数万里之外传染到了中国，而且每天都在变化，每月都在不同，几乎不知道这种流变最终会达到什么地步。对于遭受其害的人，已经难以计数；即使是讲述其危害的人，大多也是痛哭流涕，不能再多说一个字。然而，其中也有那些深受重创、极度悔恨却依然无法戒烟的人，这是因为吸烟成瘾，不容易摆脱。所以想要戒烟，应当先消除瘾症；而想要消除瘾症，必须先找到药方。现在药店里出售的戒烟药物，品种繁多，服用后似乎都有效，但不知道它们仍然含有烟膏，所以不服用后瘾症依旧存在。
最近在朋友处得到一个药方，药材容易获取且价格便宜，药效虽然缓慢但没有副作用。据说已经救了好多人，比如浙江宁波的叶某人，烟瘾本来很大，按照这个方法服用，不到半年就彻底戒断了。这个药方只使用粗大的粉甘草这一味药，不拘泥于具体分量，熬制成像烟膏一样的膏状。起初用九分烟膏，加入一分甘草膏，照常吸食。接着逐渐减少烟的比例，逐渐增加甘草膏的比例。等到甘草膏占到八九分，烟仅占一二分时，烟瘾自然就会断绝了。希望有志气的人士，都能起来尝试。如果确实有效，那么这个药方，不正是这充满烟瘴的世界中的特效良药吗！
两苍氏说：我曾经收集了十多个方子，拿出来让人试用，开始没有不灵验的，但最终没有一个人能彻底戒除。静心思考其中的原因，知道凡是一个人做事，都是靠“气”来作为统帅的，但是吸烟形成的瘾，恰好不是一天就能养成的，而人的“气”所发挥的作用，往往只是一时的，第二次就衰弱了，第三次就耗尽了，等到气力衰竭而瘾症还没有断绝，那么治疗就失败了。古人说慷慨赴义容易，从容就义难，也是这个意思。那么应该怎么办呢？回答说：方法应当持之以恒，更要忌讳拖延苟且。必须下定决心彻底戒除，并且坚持得非常坚定，然后才选择药方服药。像这样如果还不见效，我就不相信了。
又曾经听朋友说：棉花原本产于西藏，元世祖认为它可以被天下人利用，因此想把它带入中原地区。当时有一位老僧劝阻他说：利益与危害往往是相互依存的。这个东西虽然非常有利可图，但愿陛下暂时舍弃它，如果一定要传播种子进入内地，恐怕五百年后，会有另一种东西接踵而来，成为华人的祸害。元世祖没有听从，棉花于是广泛流传，而他所说的造成危害的东西，从现在来看，怀疑就是鸦片。所以有人说在棉花开花时挑选雄株，取其根部捣碎取汁饮用，就可以停止烟瘾，这似乎是事物之间的物理特性相互制约，其中原来就有联系之类的说法。根据这一点来看，鸦片的危害，或许并不完全由人为因素造成，如果能上天消除这种疾苦，突然切断来源，那么这种瘾症，哪里还需要通过刻意戒除才能去除呢。
Thai Western physicians possess a device known as "Ting Fei Mu" (Listening Wood for Lungs), which is no longer than one chi in length. When encountering patients suffering from lung diseases, they place one end against the patient's chest while resting their ear on the other end to listen.
By moving the device as they listen, carefully examining the patient's respiration and distinguishing the specific location of symptoms, they can identify the site of the disease and administer treatment accordingly.
Opium smoke is a toxic substance unprecedented in China over the past four thousand years. It has now spread from tens of thousands of miles away, changing daily and varying monthly, with its ultimate trajectory almost unknowable. The number of those harmed by it is incalculable; even those describing its harms often weep bitterly, unable to add another word. However, among them are some who suffer deep wounds and great pain, repent intensely, yet still cannot quit, because opium addiction is difficult to break. Therefore, to quit smoking, one must first eliminate the addiction; and to eliminate the addiction, one must first find a prescription. Currently, the anti-smoking medicines sold in shops come in various types, seemingly effective when taken, but unknown to the users, they still contain opium paste. Consequently, when not taken, the addiction remains unchanged.
Recently, I obtained a prescription from a friend. The herbs are easy to acquire and inexpensive. Although the effect is slow, it causes no harm. It is said to have saved many people. For example, Mr. Ye from Ningbo, Zhejiang, had a heavy opium addiction. By following this method, he completely quit within half a year. This prescription uses only one herb: coarse *Glycyrrhizae Radix et Rhizoma Praeparata cum Melle* (Prepared Licorice Root with Honey). The dosage is not fixed. It is boiled into a paste resembling opium gum. Initially, use nine parts opium paste mixed with one part licorice paste, smoking as usual. Subsequently, gradually decrease the proportion of opium and increase the licorice paste. When the mixture consists of eight or nine parts licorice paste and only one or two parts opium, the addiction will naturally cease. I hope those with determination will all rise to try it. If it proves effective, is not this prescription truly a potent medicine in this world shrouded in opium haze?
Liang Cang Shi stated: I once collected more than ten prescriptions and tested them on people. Initially, none failed to show efficacy, but ultimately, not a single person was able to break free. After quiet contemplation regarding the cause, I realized that for any human endeavor, "Qi" (Vital Energy) acts as the commander. However, opium addiction is not formed in a day, whereas the power of Qi is often momentary—it wanes upon the second attempt and is exhausted by the third. When Qi becomes depleted while the addiction persists, the attack fails. The ancients said that it is easy to die heroically for righteousness, but difficult to face death with composure; this conveys the same meaning. So, what should be done? I reply: The method must be persistent, and procrastination must be avoided. One must resolve firmly to cut it off completely and hold fast with great firmness before selecting a prescription and taking medicine. If, after doing so, it still does not work, I would not believe it.
I also heard from a friend that cotton (*Gossypii Herba*), originally produced in Tibet, was introduced to the Central Plains by Emperor Shizu of Yuan, who believed it could benefit the world. At that time, an old monk advised against it, saying: Benefit and harm often accompany each other. Although this item is highly beneficial, I beg Your Majesty to temporarily abandon it. If you insist on introducing its seeds inland, I fear that five hundred years later, another substance will follow suit and become a disaster for the Chinese people. Emperor Shizu did not listen, and cotton spread widely. The "harm" he mentioned, looking back from today, is suspected to be opium. Thus, some say that during the flowering season of cotton, one should select male plants, crush their roots to extract juice, and drink it to stop opium addiction. This seems to imply that physical properties mutually constrain each other, suggesting an inherent connection. Based on this, the harm of opium may not be entirely due to human affairs. If Heaven were to remove this affliction and abruptly cut off its source, then this addiction would not need to be forcibly quit to be eliminated.
