... In a nearby shop, on whose sign was painted a Negro smoking a cigar, I bought a sultan's tobacco, a pipe and two pink linden chubukas. Smoking drugs, I decided to put into practice and try.
The smell of tobacco was very pleasant, but the mouth was bitter and breathtaking. However, holding my heart together, I drew smoke into myself for a long time, tried to let rings and tighten. Soon the room was filled with bluish clouds of smoke, the pipe began to wheez, hot tobacco jumped, and in my mouth I felt bitterness in my head a little whirl. I wanted to stop and only look at the tube in the mirror, as, to my surprise, staggered on my feet; the room went around, and looking into the mirror, which I hardly approached, I saw that my face was pale as a canvas. As soon as I fell on the couch, I felt so nauseous and so weak that imagining that the tube was fatal to me, I thought I was dying. I was really scared and wanted to call for help and send for a doctor.
However, this fear did not last long. I soon realized what was the matter and with a terrible headache relaxed for a long time lay on the couch. With a dull understanding, gazing at the pipe lying on the polo, cigarette butts and the remains of pastry cakes, and with disappointment I thought sadly: “It is true that I am not quite big yet, if I cannot smoke like others, and that it is not fate that I see, like others, to hold a chuboob between the middle and ring finger, to tighten and let smoke through the blond mustache.
Dmitri, having come to pick me up at the fifth hour, found me in this unpleasant situation. After drinking a glass of water, however, I almost recovered and was ready to go with him.
