Turczan, James Heagy and Ted M. Hopes, Micro­ Gram .!., 3, 6-13 (Dec. 1968) Page 7, third and fourth sentences under Discussion: Change to read: "The melting point of the acid moiety found in step (g) was 148-150°c., compared to the litera­ ture, v~lue of 151°c for the melting point of benzilic acid (2); thus the benzilic acid melting point gives support to the proposed structure for 'LBJ'. Spectral evidence also supports the proposed structure". MICRO-GRAMREVISION Please re-number the pages of your copies of Micro-Gram, Volume I. Re-number pages bearing printing only.

The method was developed by Mro H.D. Beckstead and Dr. W.N. French of the Pharmaceutical Chemistry Division, Food and Druf Directorate Research Laboratories, ottawa, Canada. It was furnished ,to ~ by Mr. R.Ao Graham of the Research Laboratories, who wri tAs that it has been in use for some time in their field laboratories. LSD -BNDDagents in the East recently purchased LSD tablets which were snall, polished and were consistent in size. These have been obtai.ned in blue, red and aqua, or green, in color. It is belj_eved that colors are used by the clandestine operator to identify batches. Other LSD tablets were also recently purchased by BNDDagents:, an:i were new to our laboratory. These tablets were round, biconvex, 'approxi.mately 7/16 inch in diameter, and were white, speckled with red, green:, blue and purple fragments embedded in the t::i.bleto Average LSD content was 388 micror,rans pe~ tableto LSD continues to come in many colors. Recent powder has been lavender colored. Tablets have been charcoal grey, raspberry, pm-ple; p:$.:nkand blue, among other colors. Recently a poorly made, pink ISD tablet A.ppeared in various parts of the country bearing the so-called peace s:J111bolas a monogram. HAWAIIANBABY WOOD ROSE (Argyreia nervosa) BNDDagents in the East recently purchased capsules conta:i.nine a light brown powder alledged to be mescaline. Analysis showed it to be Arfo'oeia nervosa. It is reportedly available in pound quantities at $2 00 per pound. METHYLPHBNIDATEHCl Hethylphenidate h;itd.rochloride (Ritalin HCl), as well as the parent compound and :i.ts other salts, became a controlled drug mder the 11DACA" 1J:1endmentson April 6, 1969. PH'RNCYCLIDINE Phencyclidine arrl its salts became a controlled drug· under the NDACA" amendments on April 6, 1969. From the Archive Library of Erowid Center http://erowid.org/library/periodicals/microgram -3- PHENCYCLIDINEBASE Our Research and Special Testing Laboratory recently identified phencyclidine base submitted by a West Coast police department. The drug was reportedly involved in a non-fatal shooting, in which one member of the "Hell's Angels" shot another member fifteen times with a 45-caliber weapon. The compound is known as "Dead on Arrival" or "Dust of Angels," and may be known as "DOA". It is reportedly used by placing about fifty milligrams on a cigarette. The sample submitted was a white powder in a plastic bag, with a paper marked "1 Gram $125.00, 20 cigarettes ••. " Joseph Koles, BNDDforensic chemist, reports that the melting point of the base is 46 to 46.5 degrees. For the hydrochloride, the melt­ ing point ranges from 222 to 228 degrees C. (1) The base must be dis­ solved in a little acid before making the crystal test, according to Koles. Albert R. Sperling, Ph.D., BNDDResearch chemist, reports that the base is chloroform soluble and the ultraviolet spectrum and color tests are the same as for the hydrochloride salt. (2, 3) Dr. Sperling furnished the attached infra-red spectrogram, obtained from a film between salt plates. A potassium bromide disc of the powdered free bases gives an identical spectrum. Ref: 1.

SHORTRAPID METHOD FOR THEIDENTIFICATION OFCANNABIS H.D. Beckstead and W.N. French Food and Drug Directorate Research Laboratories Otta-wa, Canada Definition: This is a rapid, simple and.reliable method for the identifi­ cation of cannabis (marihuana) in exhibits. The procedure permits the differentiation of cannabis from other plant materials such as oregano, khat, ragweed, etc. which frequently are used as diluents. Principle: The sample is subjected to visual macroscopic and microscopic examination as well as to the Duquenois colour test and acid chloral test. The identity of cannabis is confirmed by a thin­ layer chromatographic test on a g-hexane extract of the sample material (Note 1). Additional evidence of identity may be acquired by the use of gas chromatography. ~pparatus: 1. Lowpower microscope. 2. TU:: equipment. 3. Impregnation chamber (Note 2). 4. Gas-Liquid chromatograph equipped with flame ionization detector (Note 3). Reference 1. 11ixed hashish resin standard (10 mg per ml !!-hexane) (Note 4). Materials: 2. Cannabidiol (5 mg per ml g-hexane) (Note 4). 3. Cannabinol (5 mg per ml g-hexane) (Note 4). Reagents 1. Acid chloral reagent - Dissolve 10 g chloral hydrate in 100 and ml of 20% v/v aqueous HCl. Materials: 2. Duquenois reagent - Dissolve 2 g vanillin in 100 ml of 95% ethanol. This stock solution keeps indefinitely if refriger­ ated. Immediately before use, mix 1 ml of solution with 3 drops of acetaldehyde. From the Archive Library of Erowid Center http://erowid.org/library/periodicals/microgram -5- 3. Thin-Layer Chromatoplates (a) Preparation of layers - Using standard thin-layer chroma­ tographic apparatus, coat S x 8 inch glass plates to a thickness of 0.50 rrunusing a slurry of 55 g of Kieselguhr G, 100 ml Hi and 10 ml of 1% w/v aqueous sodium carboxy­ methylce11ulose for 5 plates (Hotc 5). Allow layers to air dry in a dust-free atmosphere. activation is not necessary. (b) Impregnation with N-rnethylformamide - Mark the chromato­ plate with a sharp stylus to indicate the spotting positions with 15 cm solvent-developing distance. Immerse the plate vertically, with spotting positions uppermost, in a solution of 100 ml of N-methylformamide and 325 ml of acetone (Note 2). ~fter 5 minutes, remove the plate, allowing to drain, and air dry for 5 minutes. The impregnated plate is not susceptible to moisture pick- up, even over-night, so the sample need not be spotted immediately (Note 6). 4. Jhin-La.yer Chromatographic Solvent - Shake 100 ml of cyclo­ hexane with 10 ml of' N""!nethylformamide. Use the upper layer (Note 7). 5. Thin-Layer Chromatographic Detection Reagent - DiS$Olve 200 mg Fa.st Blue Salt B or Fast Blue Salt RR in 100 ml 50% ethanol. This reagent must be prepared fresh each day. Procedure: 1. Visual Examination of Sample Material (a) ;1acroscopic - This examination is used only to establish the presence of plant material in the exhibit. The colour, odour and form of cannabis is usually quite distinctive and different from materials used as diluents or substitutes. Examine the material under a hand lens or low power stereoscopic microscope, and separate sus­ pected marihuana plant parts from diluents. From the Archive Library of Erowid Center http://erowid.org/library/periodicals/microgram -6- {b) 1'1icroscopic - This examination is used to observe the detailed physical characteristics of the plant material using a microscope. The cannabis plant has typical cystolith hairs on the stems and underside of leaves. Extracts of cannabis (i.e. cannabis resin) usually contain considerable amounts of plant material including cystolith hairs. The latter may be readily detected by mixing a small quantity of resin with n-hexane (as in 3(b) below), transferring a drop of suspension to a microscopic slide and observing under the microscope when solvent evaporates. 2. Acid Chloral Test This test is used to detect the presence of carl:>onate deposits on the suspected plant material. Add a small drop of acid chloral reagent to a portion of the suspected plant material while observing under the microscope. Note any effervescence which may occur. The cystolith hair of cannabis contains a calcium carl:>onate deposit which liberates on treatment with co2 acid giving rise to effervescence. 3. Preparation of Sample (a) Green Plant 11aterial - Place approximately 50 mg of sample in a 10 x 75 mmtest tube, and add sufficient n~hexa.ne (0.5 ml) to just cover the sample.
