“…The episodic use of marihuana appears to result in certain consistent acute physiological effects. The most frequently reported effect is an increase in heart rate (Beaconsfield, Ginsburg & Rainsbury, 1972;Braff, Silverton, Saccuzzo & Janowsky, 1981;Cappell & Pliner, 1973;Isbell, Gorodetzsky, Jasinski, Claussen, Spulak & Korte, 1967;Jones & stone, 1970;Kiplinger, Manno, Rodda & Forney, 1971; Kochar & Hosko, 1973;Miller, Cornett & McFarland, 1976;Miller, Cornett & Nallan, 1978;Pihl, Segal & Shea, 1978;pihl, Shea & Caron, 1978;Rafaelsen, Bech, Christiansen, ChristruPr Nyboe & Rafaelsen, 1973;Renault, Schuster, Heinrich & Freeman, 1971;Roth, Tinklenberg, Kopell & Hollister, 1973;Weil, Zinberg & Nelsen, 1968;Weiss, Watanabe, Lemberger, Tamarkin & Cardon, 1972). other effects which also have been documented are: A decrease in stability of stance, as measured by a wobble board (Evans, Martz, Brown, Rodda, Kiplinger, Lemberger & Forney, 1973;Kiplinger et al, 1971); dilation of the conjunctual blood vessels (blood-shot eyes) (Kiplinger et a1., 1971;Weil et al, 1968); an increase in forearm blood flow (Beaconsfield et al, 1972;Weiss et al, 1972); and a decrease in hand steadiness (Clark, Hughes & Nakashima, 1970).…”

“…The acute effects of cannabis and THC consumption on blood pressure are more variable, with potential implications for perfusion during exercise. Investigators have reported increases in systolic and diastolic pressure [ 41 , 42 , 53 , 59 , 61 , 64 , 65 , 76 – 78 , 83 ], reductions in blood pressure [ 60 , 63 ], or no changes in blood pressure [ 43 , 58 , 59 , 62 , 63 , 73 – 75 , 81 , 88 – 90 ] following cannabis or THC consumption. Unlike HR, it appears that pressure responses during exercise are not affected following a single instance of cannabis consumption [ 43 ].…”

Cannabis and Athletic Performance

Cannabis is widely used for both recreational and medicinal purposes on a global scale. There is accumulating interest in the use of cannabis and its constituents for athletic recovery, and in some instances, performance. Amidst speculation of potential beneficial applications, the effects of cannabis and its two most abundant constituents, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), remain largely un-investigated. The purpose of this review is to critically evaluate the literature describing the effects of whole cannabis, THC, and CBD, on athletic performance and recovery. While investigations of whole cannabis and THC have generally shown either null or detrimental effects on exercise performance in strength and aerobic-type activities, studies of sufficient rigor and validity to conclusively declare ergogenic or ergolytic potential in athletes are lacking. The ability of cannabis and THC to perturb cardiovascular homeostasis warrants further investigation regarding mechanisms by which performance may be affected across different exercise modalities and energetic demands. In contrast to cannabis and THC, CBD has largely been scrutinized for its potential to aid in recovery. The beneficial effects of CBD on sleep quality, pain, and mild traumatic brain injury may be of particular interest to certain athletes. However, research in each of these respective areas has yet to be thoroughly investigated in athletic populations. Elucidating the effects of whole cannabis, THC, and CBD is pertinent for both researchers and practitioners given the widespread use of these products, and their potential to interact with athletes’ performance and recovery.

Stroke after heavy marijuana smoking.

Stroke

I examined two young men who developed cerebral infarction associated with heavy marijuana smoking. Both were light tobacco smokers, but they did not drink alcohol or use other street drugs. Diagnostic work-up for nonatherosclerotic causes of stroke was unremarkable. I postulate that marijuana-associated alterations in systemic blood pressure resulted in vasospasm, leading to strokes in these patients. (Stroke 1991;22:406-409) S troke associated with drug abuse has been reported frequently. 1 Although the incidence and prevalence of cerebral infarction and intracranial hemorrhage associated with drug abuse is uncertain, case series have provided extensive documentation of stroke occurring with the use of street drugs, especially cocaine, amphetamines, "Ts and blues," anabolic steroids, lysergic acid diethylamide, barbiturates, alcohol, and heroin.2 -8 However, an acute neurological deficit following heavy marijuana smoking has been reported infrequently. 13 I examined two young men who had cerebral infarction during heavy marijuana smoking. Case Reports Case 1A previously healthy 34-year-old right-handed white man experienced the sudden onset of dizziness, left arm and leg weakness, and slurred speech while smoking a marijuana cigarette. There was no headache, and he denied the use of other street drugs and alcohol. He had smoked less than one pack of tobacco cigarettes and up to seven marijuana cigarettes per day for 15 years. Recently, he had increased his marijuana smoking from seven to a 14 cigarettes per day. There was no family history of stroke, heart disease, hypertension, diabetes mellitus, migraine headache, lupus erythematosus, autoimmune disorders, or sickle cell disease. This patient's blood pressure was 164/110 mm Hg and his pulse was 104 beats/min on admission. Neurological examination performed <,2 hours after the onset of symptoms showed severe dysarthria, rightleft disorientation, and acalculia. Cranial nerve exam- Received July 20, 1990; accepted November 20, 1990. ination revealed left lower facial weakness. Strength of the left leg was 0/5, strength of the left arm was 1/5, and there was loss of pinprick and temperature sensation on the left side. Results of the following laboratory studies were within normal ranges: complete blood count; platelet count; fibrinogen level; prothrombin time; partial thromboplastin time; concentrations of serum glucose, electrolytes, cholesterol, high density lipoprotein, low density lipoprotein, and triglycerides; liver and renal function tests; concentrations of metanephrine and catecholamines; erythrocyte sedimentation rate; presence of antinuclear antibodies and rheumatoid factor; VDRL; concentrations of C3 and C4; platelet function tests; lupus anticoagulant, anticardiolipin antibody, and protein C; human immunodeficiency virus titer; and concentration of antithrombin-3. The results of 24-hour Holter monitoring and echocardiography were normal. The results of renal angiography, done because of the patient's hypertension, were also normal. He did not con...
